This study aims to analyze the technical, environmental, economic and thermal comfort impacts of implementing passive measures and heating systems in Ciudad Verde, a large-scale social housing project located at the periphery of Bogota, Colombia.

A system dynamics (SD) model is proposed to evaluate scenarios through counterfactual experiments, including technical, environmental and economic components. Model inputs are obtained from building energy simulation models and data collected from official reports, public policy documents and construction records.

Results suggest that the use of heating systems is the best choice to achieve thermal comfort conditions throughout the day. However, both the capital expenditures and CO₂ emissions associated with such system make their adoption very difficult. In line with that, the use of heating systems in combination with passive measures stands out as a viable solution since their costs are affordable and their use contributes to reducing CO₂ emissions.

The proposed model recreates the dynamics underlying social housing construction processes, the adoption of heating systems and passive measures in low-income dwellings and their corresponding impact on CO₂ emissions and indoor thermal comfort conditions. The model can be employed as a support tool in the formulation of social housing policies associated with thermal comfort specifications. In this way, the model represents a first step toward incorporating thermal-related variables into the decision-making processes related to social housing planning and development.

Purpose – Since the mid-1980s, unemployment policy reforms in Europe and throughout the rich democracies have stressed publicly supported activation of the unemployed through both reductions in perceived disincentives to work as well as commitments for improved training, employment services, and related policies. In this chapter, I systematically explore the domestic and international political economic sources of these policy changes.

Methodology/approach – I test a set of hypotheses – original and derivative – about the domestic and international determinants of labor market policy change through pooled time-series cross-section analysis of 1980-to-2002 annual data from 18 capitalist democracies. The dependent variables consist of national spending on active labor market policy, measures of passive unemployment compensation benefits, and the ratio of active to passive unemployment program spending. Causal models account for spatial diffusion of policy reforms as well as core political and economic determinants of policy change.

Findings – I find that Left party governments and coordinated market institutions buoy resources for active labor market programs, maintain relatively generous passive unemployment supports and entitlements, and, at the same time, foster a shift to more active social policy. International trade openness promotes generous active labor market policies while more left-leaning voters and veto points within the polity significantly constrain reductions in unemployment benefits and entitlement rights. De-industrialization reinforces policy reforms toward activation while high unemployment rates engender cuts in passive unemployment benefits and eligibility conditions.

Originality/value – Overall, the chapter demonstrates that the economic effects on policy change notwithstanding, politics fundamentally matters: domestic political dynamics and variations in institutions explain the preponderance of the change (or lack thereof) in unemployment policy.

Upper-limb joint kinematics are highly complex and the kinematics of rehabilitation exoskeletons fail to reproduce them, resulting in hyperstaticity and human–machine incompatibility. The purpose of this paper is to design and develop a compatible exoskeleton robot (Co-Exos II) to address these problems.

The configuration synthesis of Co-Exos II is completed using advanced mechanism theory. A compatible configuration is selected and four passive joints are introduced into the connecting interfaces based on optimal configuration principles. A Co-Exos II prototype with nine degrees of freedom (DOFs) is developed and still owns a compact structure and volume. A new approach is presented to compensate the vertical glenohumeral (GH) movements. Co-Exos II and the upper arm are simplified as a guide-bar mechanism at the elevating plane. The theoretical displacements of passive joints are calculated by the kinematic model of the shoulder loop. The compatible experiments are completed to measure the kinematics of passive joints.

The compatible configuration of the passive joints can effectively reduce the gravity influences of the exoskeleton device and the upper extremities. The passive joints exhibit excellent compensation effect for the GH joint movements by comparing the theoretical and measured results. Passive joints can compensate for most GH movements, especially vertical movements.

Co-Exos II possesses good human–machine compatibility and wearable comfort for the affected upper limbs. The proposed compensation method is convenient to therapists and stroke patients during the rehabilitation trainings.

The purpose of this paper is to determine how CEO overconfidence influences firm’s future risk in a sample of Chinese listed firms. It further examines the moderating effect of institutional investors on the association between CEO overconfidence and future firm risk.

The initial sample consists of Chinese A-share issuing firms listed on Shanghai and Shenzhen Stock Exchanges during the period starting from 2000 to 2017. This study classifies a CEO as overconfident if the forecasted profits of the firm are greater than the actual profits for majority of the time during the tenure of the CEO. Ordinary least squares regression is used as the primary estimation method for generating the results, however, firm fixed effects and two-stage least squares regressions have also been used for verifying the robustness of the results.

The results demonstrate that CEO overconfidence leads to an escalation in firm’s risk level over the subsequent years. However, the intensity of this positive association is weaker in state-owned firms. Analysis of the moderating effect of institutional investors reveals that only active institutional investors, specifically mutual funds and foreign institutional investors, play their governance role in reducing the effect of CEO overconfidence on firm’s risk level. Furthermore, the moderating effect of active institutional investors is weaker in state-owned firms.

The empirical evidence obtained by this study suggests that CEOs should exercise extreme diligence in decision-making. They must analyze a situation based on realistic facts and figures, rather than having misperception about their excessive abilities in controlling the outcomes of a situation. The findings also imply that regulators and policymakers should formulate strategies for motivating mutual funds and foreign investors to increase their shareholding in Chinese firms.

To the best of the authors’ knowledge, this is the first study that examines the impact of CEO overconfidence on future firm risk, not the current firm risk. Besides, literature regarding the role of external governance mechanisms in the context of behavioral biases is extremely scant. This study contributes to the literature by analyzing how the association between CEO overconfidence and firm’s future risk is influenced by the institutional investors’ ownership.

This chapter investigates attention theory by examining retail investors' true intention to purchase. Attention theory indicates that investors, and especially retail investors, typically invest in stocks about which they are aware. Previous studies test attention theory by analyzing stock price behavior or trading volume. However, stock prices and trading volume are primarily driven by institutional investors rather than retail investors. We examine investor attention using initial public offering (IPO) subscriptions in Taiwan because only retail investors are allowed to subscribe to Taiwanese IPOs. We use media coverage as a measure of passive retail investor attention and Google search volume as a measure of active retail investor attention. Our results reveal that active attention has a more profound relationship with retail investor IPO subscriptions than passive attention does. Additionally, information about the value of IPOs taken from trading prices in the pre-IPO market mitigates the effects of attention theory.

Due to the vital role of innovation for firms to respond to the change and achieve competitive advantage, the purpose of this study is to investigate the influence of knowledge-oriented leadership (KOL) on innovation performance via the mediating role of knowledge sharing (KS). This study also explores the moderating role of organizational justice in the relationship between KS and innovation performance.

Analysis of moment structures and structural equation modeling are applied to examine the relationship among the latent factors in the proposed research model using data collected from 335 participants in 121 manufacturing and service firms in Vietnam.

The findings revealed that KOL serves as a key precursor to foster innovation performance directly or indirectly through active and passive KS behaviors. In addition, the paper highlights the moderating role of organizational justice in strengthening the impact of KS activities on innovation performance.

By highlighting the important role of KOL for stimulating KS behaviors, this paper provides a valuable understanding and novel approach for firms to improve innovation performance. The research findings support the idea that building a climate of justice is crucial to enhance the effects of KS on innovation performance.

This study contributes to bridging the research gaps in the literature and advances the insights of how KOL directly and indirectly stimulates innovation performance via mediating roles of active and passive KS processes under the climate of justice.

Due to the vital role of frugal innovation (FI) for firms in developing and emerging economies, the purpose of this study is to investigate the effect of transformational leadership (TL) and knowledge sharing (KS) on FI of firms in supply chains. This study aims to bring deeper insight on the correlation among the constructs by exploring and analyzing the moderating effect of collaborative culture (CC) in the KS-FI relationship.

The paper used the quantitative approach and structural equation modeling (SEM) to test the relationship among the latent factors in the proposed research model using data collected from 381 participants in 116 manufacturing and service firms.

The findings revealed that TL might be an important precursor to induce significant influences on FI directly or indirectly through its effect on active and passive KS processes in supply chains. In addition, the paper highlights the moderating role of CC in strengthening the impact of KS processes on FI.

The paper provides a valuable understanding and novel approach for managers to improve firms' FI capability through leadership practice and KS processes. The research findings support the idea that FI capability of firms in developing and emerging nations will be significantly enhanced if leaders are interested in practicing TL style and fostering a climate of collaboration within organization.

This study contributes to bridging research gaps in the literature and advancing the insights of how TL directly and indirectly fosters FI via mediating roles of active and passive KS processes in supply chains under the climate of collaboration.

The purpose of this paper is to investigate if earnings management affects the trades of different investors prior to earnings announcements.

Using a unique account-level trading data set from the Chinese stock market, the author investigates the different investor trading patterns prior to earnings announcements.

The author obtains direct evidence to show that: first, institutional investors, particularly active ones, tend to sell (buy) stocks before negative (positive) earnings surprises; second, institutional investors buy stocks intensively with the lowest earnings management and the highest earnings surprises, and the trading patterns are primarily driven by active institutions. No significant trading pattern is observed on the stocks with negative earnings surprises; and third, the author uses a natural experiment in accordance with the Chinese accounting standards reform to address endogeneity, and the causality of the results still holds.

The findings provide clear evidence by emphasizing the importance of earnings management in the formulation of investor decisions.

The authors aim to measure the effects of ambidextrous innovation and its mix strategy on organizational obsolescence with the moderating roles of environmental turbulence.

Hierarchical regression analysis was used to test the hypotheses on the basis of the survey data of 198 firm employees in China.

Both exploratory and exploitative innovations significantly restrain organizational obsolescence. The complementary strategy of ambidextrous innovation is negatively correlated to organizational obsolescence, but the impact of balanced strategy is not significant. Environmental turbulence negatively moderates the relationship between exploratory innovation and organizational obsolescence, whereas it cannot moderate the effect of exploitative innovation.

The empirical and conceptual findings have important implications for organizations countering obsolescence through the construction of a mix strategy of ambidextrous innovation. This study enriches and extends obsolescence theory by introducing the joint mechanism of ambidextrous innovation and environmental turbulence.

Proper performance assessment of residential building renovation is crucial to sustainable urban development. However, a comprehensive review of the literature in this research domain is lacking. This study aims to uncover the study trend, research hotspots, prominent contributors, research gaps and directions in this field.

With a hybrid review approach adopted, relevant literature was examined in three stages. In Stage 1, literature retrieved from Scopus was screened for their relevance to the study topic. In Stage 2, bibliographic data of the shortlisted literature underwent scientometric analyses by the VOSviewer software. Finally, an in-depth qualitative review was made on the key literature.

The research hotspots in performance assessment of residential building renovation were found: energy efficiency, sustainability, thermal comfort and life cycle assessment. After the qualitative review, the following research gaps and future directions were unveiled: (1) assessments of retrofits incorporating renewable energy and energy storage systems; (2) evaluation of policy options and financial incentives to overcome financial constraints; (3) establishment of reliable embodied energy and carbon datasets; (4) indoor environment assessment concerning requirements of COVID-19 prevention and involvement of water quality, acoustic insulation and daylighting indicators; and (5) holistic decision-making model concerning residents' intentions and safety, health, well-being and social indicators.

Pioneered in providing the first comprehensive picture of the assessment studies on residential building renovations, this study contributes to offering directions for future studies and insights conducive to making rational decisions for residential building renovations.
