Abstract

Purpose

The purpose of this paper is to discuss several obstacles that can reduce the effectiveness of managerial coaching. Furthermore, the paper highlights the role played by various stakeholders [i.e. the organization, senior leaders, the human resources (HR) function and managers] in overcoming or reducing the potency of such obstacles.

Design/methodology/approach

The views presented here have been derived from the authors’ professional experience in managerial coaching and a review of the literature on managerial coaching.

Findings

The authors discuss six common obstacles to effective managerial coaching: time for coaching, willingness to coach, ability to coach, employees’ ability and willingness, societal expectations and the intrusion of technology. They describe the critical role of various stakeholders (i.e. the organization, senior leaders, the HR function and line managers) in overcoming or mitigating the impact of such obstacles, thus contributing to effective managerial coaching.

Originality/value

A discussion of the obstacles to effective managerial coaching and the role of stakeholders in managerial coaching is valuable for organizations that seek to enhance the performance of employees through managerial coaching.

Abstract

Purpose

The purpose of this paper is to discuss whether, in entrepreneurship disciplines, professors address equally the positive and negative aspects associated with being an entrepreneur. The literature shows that entrepreneurship professors are enthusiastic about entrepreneurial action, and there may be a bias toward predominant emphasis on positive aspects.

Design/methodology/approach

The case study strategy was used to analyze disciplines that qualify entrepreneurship professors. The content analysis technique was applied to the description of the discipline contents and texts from the most frequently used literatures. The selected case (the country) satisfied the condition of having a regulatory agency that evaluates courses and also provides descriptive records of the disciplines that are taught.

Findings

It was observed that the topics discussed in the disciplines, as well as the texts of the most frequently used articles, contain a higher volume of messages that are positive and favorable toward the entrepreneurial act. Negative effects or aspects of entrepreneurship are addressed superficially.

Practical implications

This article provides important reflections on the activities of those who teach entrepreneurship, as well as editors and reviewers of entrepreneurship journals. Regarding the former, when preparing the content of their disciplines, and for the latter, when evaluating articles, bearing in mind that their articles are also used by students and professors from countries with less developed economies.

Originality/value

Exploring the myths of entrepreneurship, especially the claim that everyone is capable of becoming an entrepreneur and that entrepreneurship promotes economic development, the risk of becoming an entrepreneur was addressed, especially in countries with less developed economies. From this viewpoint, issues regarding the responsible teaching of entrepreneurship were addressed, along with the need to focus equally on the favorable and unfavorable aspects of entrepreneurship.

Abstract

Purpose

The most common methodology to estimate erosivity is using rainfall data obtained from rain monitoring stations. However, the quality of this estimation may be compromised due to low density, operational problems and maintenance cost of rainfall monitoring stations, common problem encountered in developing countries such as Brazil. The objective of this study was to evaluate the applicability of pluviometric data obtained by TRMM satellite images for the spatiotemporal characterization of erosivity in the state of Espírito Santo (Brazil).

Design/methodology/approach

For this, rainfall data and annual and monthly erosivities of 71 rainfall stations were statistically compared with those from TRMM images.

Findings

For this, rainfall data and annual and monthly erosivities of 71 rainfall stations were statistically compared with those from TRMM images. The estimate proved that TRMM is efficient since the NSE values were higher than 0.70 and the coefficient of determination was higher than 0.77 for monthly and annual erosivities, but in most months and yearly, erosivity was overestimated.

Practical implications

The use of satellite images to estimate rainfall allowed the spatial representation over time (months) of the oscillating degree of erosivity in the state of Espírito Santo (Brazil). The spatialization may provide an identification of areas and periods in which are essential for the implementation of land use management in order to minimize environmental problems related to soil loss.

Originality/value

The technique applied may be an alternative to overcome common problems on rainfall monitoring station, such as low density, low data reliability, high manutention and maintenance cost and operational problems.

Abstract

Purpose

The purpose of this paper is to develop and test control methods for real‐time automatic presser‐foot force control in industrial sewing machines. In this work, a closed‐loop controller that controls presser‐foot maximum vertical displacement is presented and compared to existing solutions that adjust force depending on sewing speed. Automatic force control can reduce problems such as stitch irregularity, stitch distortions and material damage, besides making material handling easier.

Design/methodology/approach

An electromagnetic force actuator was integrated in an industrial lockstitch machine. A computer‐based control system was designed implementing either speed‐variable force control, closed‐loop control, or emulating a traditional constant‐force system. Maximum presser‐foot displacement values were measured and analysed in relevant sewing situations, and seam quality was assessed.

Findings

Constant‐force control does not allow optimal force setting at all speeds. Speed‐variable force control is an improvement, but requires empirical setting of the speed‐force relation, not always assuring optimal operation. Closed‐loop control adapts force to the requirement of each sewing situation more precisely. Sewing quality is good and material handling is eased.

Research limitations/implications

The actuator has to be optimised regarding response time and maximum force. Some aspects in the behaviour of the control system and actuator have to be further studied.

Practical implications

The proposed control system enables the automatic setting and adaptation of force to all sewing situations, making material handling easier at low speeds without compromising feeding performance at high speed. The closed‐loop controller may be used as a teach‐in system for speed‐dependent control.

Originality/value

This is the first prototype of a closed‐loop control system for presser‐foot force on a lockstitch sewing machine and the first comparative study of control methods for presser‐foot force control.

Abstract

Purpose

This study investigates the presence of herding in the Brazilian stock market between 2012 and 2020 and associates it with the volume of searches on the Google platform.

Design/methodology/approach

Following methodologies are used to investigate the presence of herding: the Cross-Sectional Standard Deviation of Returns (CSSD), the Cross-Sectional Absolute Deviation (CSAD) and the Cross-Sectional Deviation of Asset Betas to the Market.

Findings

Most of the models detected herding. In addition, there was a causal relationship between peaks in Google search volumes and the incidence of herding across the whole period, especially in 2015 and 2019.

Originality/value

This study suggests that confirmation bias influences investors' decisions to buy or sell assets.

Abstract

This chapter differentiates stress from generalized anxiety, discussing the nature and prevalence of each among college students. The chapter then delves into generalized anxiety in detail, covering instruments that measure generalized anxiety, cultural considerations associated with generalized anxiety and the causes, consequences, prevention and treatment of generalized anxiety among college students. The next section of the chapter focuses on social anxiety among college students, similarly addressing its defining characteristics, prevalence, cultural considerations, causes, consequences, prevention and treatment. The final section of the chapter follows a similar structure in discussing posttraumatic stress disorder (PTSD) among college students. Throughout the chapter, attention is devoted to neurotransmitters and brain structures that are involved in anxiety and its treatment through antianxiety medications. Case examples are used to help bring theoretical concepts and research findings to life.

Abstract

This chapter addresses one of the most common and long-standing problems among college students, namely depression, as well as a potential consequence of depression, suicide. A formal definition of depression is presented, and symptoms of depression are discussed. Notably, clinical depression is differentiated from “feeling down” or having “the blues.” Common measures of depression for college students are described, and the current prevalence of depression among college students is explored, along with data pertaining to trends and trajectories. Particular attention is devoted to differences in rates and severity of depression among students of various ethnicities, gender identities, disabilities and sexual orientations. Next, the chapter covers various theories about and studies on the causes and consequences of depression, as well as preventive and remedial efforts that students can engage in to minimize the adverse effects of depression. The chapter concludes with a focus on college student suicide, including its prevalence, predictors of suicidal thoughts and behaviors and prevention and treatment of college student suicide.

Abstract

Purpose

This paper, based on the 2022 Master Class delivered at the 50th National Economic Meeting organized by ANPEC, discusses how post-Keynesian macroeconomics and New Developmentalism complement each other to understand middle-income economies' development in financial globalization. It summarizes my academic reflection about the advance in post-Keynesian thinking to develop macroeconomics for peripheral middle-income economies.

Design/methodology/approach

As part of this reflection, I first bring up the idea of a developmental convention and, next, how peripheral financialization impacts the elaboration of this convention. Given the asymmetric configuration of the international financial system and the context of hierarchical currencies, I discuss the challenge of overcoming underdevelopment in peripheral economies. The post-Keynesian macroeconomics and advances in the structuralist debate provide the analytical tools to understand how peripheral economies develop virtuous or vicious growth cycles. At the end of the paper, I present some comments on the stagnation of the Brazilian economy.

Findings

The growth strategy with foreign savings does not provide the conditions for middle-income economies to operate with sufficient economic policy autonomy to promote productive transformation. To this end, a developmental convention should replace the neoliberal convention that has dominated since the 1970s.

Originality/value

The dynamics of peripheral, middle-income economies, often influenced by international liquidity flows, are a crucial area of study. This research underscores the importance of understanding these dynamics, as it forms the basis for economic policy recommendations. The paper also highlights the inadequacy of the growth strategy with foreign savings in the current configuration of the international financial system, emphasizing the need for middle-income economies to operate with greater economic policy autonomy to foster productive transformation.
