Abstract

The impending demographic shift in the United States (Vespa et al., 2020) will require leadership educators to reexamine the relationship between diversity and inclusive leadership. Our literature review revealed inclusive leadership has historically not been viewed with a diversity perspective. To better understand the link between diversity and inclusive leadership, we reviewed how leadership scholars, researchers, and authors have described the attributes and impacts of inclusive leaders. Through inductive coding, we identified seven attributes (i.e., characteristics and actions) of inclusive leaders. When these attributes are acted upon, inclusive leaders create various impacts on followers. These impacts are applied to Shore et al.’s (2011) inclusion framework. Both the attributes and impacts are presented to provide information and tools to better equip leadership educators with the knowledge to foster classroom inclusion in diverse classroom environments.

Abstract

Purpose

An appropriate equivalent model is the key to the effective analysis of the system and structure in which permanent magnet takes part. At present, there are several equivalent models for calculating the interacting magnetic force between permanent magnets including magnetizing current, magnetic charge and magnetic dipole–dipole model. How to choose the most appropriate and efficient model still needs further discussion.

Design/methodology/approach

This paper chooses cuboid, cylindrical and spherical permanent magnets as calculating objects to investigate the detailed calculation procedures based on three equivalent models, magnetizing current, magnetic charge and magnetic dipole–dipole model. By comparing the accuracies of those models with experiment measurement, the applicability of three equivalent models for describing permanent magnets with different shapes is analyzed.

Findings

Similar calculation accuracies of the equivalent magnetizing current model and magnetic charge model are verified by comparison between simulation and experiment results. However, the magnetic dipole–dipole model can only accurately calculate for spherical magnet instead of other nonellipsoid magnets, because dipole model cannot describe the specific characteristics of magnet's shape, only sphere can be treated as the topological form of a dipole, namely a filled dot.

Originality/value

This work provides reference basis for choosing a proper model to calculate magnetic force in the design of electromechanical structures with permanent magnets. The applicability of different equivalent models describing permanent magnets with different shapes is discussed and the equivalence between the models is also analyzed.

Abstract

Purpose

The adoption of social media has been extensively discussed. However, to explain the adoption of traditional social media, considering the benefits and risks accumulated from the experiences of social media use, the extent literature is limited. Thus, this paper investigated the act of traditional social media users’ switching behavior from a dynamic perspective and the level of information privacy concerns and social media privacy to measure the risks and benefit accumulated from this dynamic process.

Design/methodology/approach

This study of Facebook and Twitter users, who are regarded as representative of traditional social media, are selected as research targets surveyed and were required to answer a specially designed questionnaire in order to determine their general feeling on social media platforms they currently use. As a part of this process, quota sampling was used to collect different samples based on gender and age. In this paper, t-test, one-way ANOVA and multiple comparisons were used for the statistical analysis, conducted through SPSS.

Findings

Information privacy concerns and social media dependency affect the adoption of social media. Secondly, social media dependency is a more salient determinant for social media adoption. Therefore, social media firms should pay more attention to enhancing user dependency of social media by increasing user involvement of social media.

Originality/value

This study intends to conduct a research design that provides an overall and holistic understanding of user usage experience. To do this, it investigates the intensity of switching behavior through the level of dependency and the level of information privacy concern that users inevitably exhibit through the use of social media over long time.

Abstract

Purpose

This paper examines the asymmetric effects of inflation and interest rate on stock prices in Indonesia.

Design/methodology/approach

Variables such as interest rate, inflation rate, gross domestic product (GDP), and exchange rate were tested using the time-series data fitted to the Nonlinear Autoregressive Distributed Lag (NARDL) model. The asymmetric effects of interest rate and inflation rate were estimated in two separate models, with data covering the period from 1997:Q1 to 2023:Q3.

Findings

The results indicated that interest rate exhibit asymmetric effects on stock prices in both the short and long run. Conversely, no asymmetric effect was identified for the inflation rate model. The NARDL result of the asymmetry interest rate model revealed that both positive and negative changes in interest rate have a negative impact on stock prices in Indonesia. Notably, stock prices were positively and significantly influenced by both economic growth and exchange rate. The results suggested that policymakers should respond more proactively by adjusting interest rate in line with stock price movements.

Originality/value

This study diverges from previous studies by employing a general equilibrium theoretic model to link output with stock returns and extending it to include macroeconomic variables relevant to stock price determination. This study uniquely examined the asymmetric effects of monetary policy variables in Indonesia, particularly by comparing the asymmetric effects of inflation and interest rate.

Abstract

Purpose

Building on social exchange theory and relational leadership theory, this paper proposes a model of inclusive leadership in higher education institutions. Together with an attempt to examine the impact of inclusive leadership on extra-role behaviors of academic staff, the paper aims to test the intervening mechanism of organizational learning among the aforementioned relationships.

Design/methodology/approach

Data were collected from 227 academic staff working in the Palestinian higher education institutions. Partial least squares (PLS-SEM) analysis technique was utilized to examine the hypotheses.

Findings

The findings reveal that inclusive leadership exerts a positive effect on extra-role behaviors (organizational citizenship behaviors and innovative work behaviors) in the Palestinian higher education setting. Moreover, the findings show that organizational learning plays a significant mediating role among the relationships examined

Practical implications

Academic communities are increasingly diverse. This diversity requires a work environment in which employees take on additional work roles. In response to this diversity, managers of higher education institutions should be concerned about the roles and practices of inclusive leaders. In addition, higher education institutions need to be learning organizations since this would help to mitigate this diversity and create a working atmosphere characterized by continuous learning, collaboration and dialogue.

Originality/value

In higher education, most of the literature on inclusive academic leadership is mainly theoretical. Furthermore, organizational learning in higher education research is based on anecdotal perspectives (Dee and Leišyte, 2016). To this end, this paper is novel, as it is one of few studies to empirically investigate inclusive leadership and extra-role behaviors via organizational learning in a non-western academic context.

Abstract

Purpose

Monocytes are a leukocytes’ subset that plays an important role in immunity. Protein kinase B (AKT) is involved in monocytes' survival, proliferation and differentiation. Using phorbol 12-myristate 13-acetate (PMA) as an inducer for cell line U937 differentiation into macrophage-like cells may be used as a model for cancer cell therapy or other biomedical research studies. The authors investigated the Akt1 signaling pathway's involvement with PMA as a differentiating agent and survival in the U937 cell line.

Design/methodology/approach

PMA was utilized to stimulate the differentiation of the U937 cell line into macrophage-like cells at a concentration of 10 nM. Akt1-phosphorylated Serine 473, Bad-phosphorylated Serine 136 and Caspase9-phosphorylated Serine 196 were tested by flow cytometry for the involvement of the Akt1 signaling pathway during differentiation in addition to the expression of CD14, CD206 and CD83. DNA cell cycle variation analysis was done using PI staining and cell viability and apoptosis detection using Annexin V and PI flow cytometry.

Findings

There was a decrease in phosphorylated Akt1 and Bad activation and an increase in Caspase9 activation, with an increase in surface markers CD14, CD206 and CD83 acquired by PMA-differentiated cells. DNA cell cycle analysis revealed cell accumulation in the G2/M phase and fewer cells in the S phase of PMA-induced U937. Apoptosis induction for Ly294002 or Wortmannin-inhibited cells and part of PMA-induced cells were detected.

Originality/value

These results may be used to create a model for biomedical research studies and advance the understanding of the mechanism involving differentiation of the U937 cell line.

Abstract

Purpose

This study aims to determine the influence of bruise damage generated from the impact test on the physical, chemical and nutritional responses of tomato fruit.

Design/methodology/approach

The impact loading was applied from different heights. The impact energies for 20, 40 and 60 cm drop heights were 129.59, 259.18 and 388.77 mJ, respectively. The injured samples were kept for 48 hours at low (10 °C) and ambient (22 °C) storage temperatures. Weight loss, firmness, color, total soluble solids (TSS), lycopene and carotenoids were measured before the impact test (day 0) and after 48 hours of the impact and storage.

Findings

The drop height of 60 cm and storage at 22 °C showed the highest values in the bruised area. The impact from the 60 cm drop height significantly reduced weight, lightness, yellowness, hue, firmness, lycopene and carotenoids, particularly at 22 °C storage condition. Redness (a*) and color index (CI) showed a remarkable increase (p < 0.05) at 22 °C on tomatoes affected from the highest impact level (388.77 mJ) after 48 hours of storage. No pronounced significance was seen between TSS and drop heights. This study has confirmed that tomato bruising for a short-term storage period induces physiological changes at different storage temperature conditions.

Originality/value

The study can confirm the crucial role of inappropriate handling in increasing fresh produce loss within short-term storage. Also, this research can be considered as a guideline for transporters, handlers, processors, distributors and horticulture researchers in the fresh produce supply chain during postharvest operations.

Abstract

Purpose

Building on behavioral agency theory, the authors explore the role played by corporate governance characteristics as drivers of the diversification strategies of family firms. Specifically, this study aims to investigate the effects of board size and board gender diversity on the likelihood that family firms will execute a diversifying acquisition vis-à-vis a related acquisition. Furthermore, the authors investigate the contingency effects played by foreign directorship and the firm’s listing status.

Design/methodology/approach

The hypotheses are tested on an original sample of 213 cross-border acquisitions executed by Italian family firms between 2008 and 2021.

Findings

The findings suggest that both large board sizes and greater gender diversity positively affect the diversification of family firms. While the presence of foreign directors magnifies the positive effect of board size, gender diversity discourages diversification in the case of listed firms.

Originality/value

The originality of this study is twofold. First, while prior literature has mostly focused on the family vs nonfamily dichotomy, this paper contributes to an emergent line of research investigating the heterogeneity among family firms’ corporate strategy decisions. Second, by exploring the corporate governance-diversification link in the context of family business, the authors answer to recent calls that diversification by family firms deserves further investigation in light of its highly controversial nature in terms of socioemotional wealth implications and potential mismatch among multiple objectives.

Abstract

The recommendation of the analyst report is not only limited to a small number of ratings, but also biased toward a buy opinion with the absence of sell opinion. As an alternative to this, this paper aims to extract analysts' textual opinions embedded in the report body through text analysis and examine the profitability of investment strategies. Analyst opinion about a firm is measured by calculating the frequency of positive and negative words in the report text through the Korean sentiment lexicon for finance (KOSELF). To verify the usefulness of textual opinions, the author constructs a calendar-time based portfolios by the analysts' textual opinion variable of each stock. When opinion level is used, investment strategy has no significant hedged portfolio return. However, hedged portfolio constructed by opinion change shows significant return of 0.117% per day (2.57% per month). In addition, the hedged return increases to 0.163% per day (3.59% per month) when the opening price is used instead of closing price. This study show that the analysts’ opinion extracted from text analysis contains more detailed spectrum than recommendation and investment strategies using them give significant returns.
