A main cause of defects within material extrusion (MatEx) additive manufacturing is the nonisothermal condition in the hot end, which causes inconsistent extrusion and polymer welding. This paper aims to validate a custom hot end design intended to heat the thermoplastic to form a melt prior to the nozzle and to reduce variability in melt temperature. A full 3D temperature verification methodology for hot ends is also presented.

Infrared (IR) thermography of steady-state extrusion for varying volumetric flow rates, hot end temperature setpoints and nozzle orifice diameters provides data for model validation. A finite-element model is used to predict the temperature of the extrudate. Model tuning demonstrates the effects of different model assumptions on the simulated melt temperature.

The experimental results show that the measured temperature and variance are functions of volumetric flow rate, temperature setpoint and the nozzle orifice diameter. Convection to the surrounding air is a primary heat transfer mechanism. The custom hot end brings the melt to its setpoint temperature prior to entering the nozzle.

This work provides a full set of steady-state IR thermography data for various parameter settings. It also provides insight into the performance of a custom hot end designed to improve the robustness of melting in MatEx. Finally, it proposes a strategy for modeling such systems that incorporates the metal components and the air around the system.

The authors reviewed studies of validated tools to screen for cognitive impairment among prisoners. The purpose of this paper is to assist organisations in identifying cognitive impairment in correctional facilities.

A targeted literature review identified peer-reviewed articles on screening of adults in jails, prisons, police watch-houses, custody suites, rehabilitation facilities and forensic settings or community settings for offenders. Validation of screening tools in secure settings, psychometric properties and cultural discrimination is included in this review.

Eight screening tools are considered suitable for use in correctional settings. Two screening tools are recommended for cognitive impairment, one is recommended for adaptive functioning assessment and one is recommended for screening of brain injury. Two screening tools are noted to be subject to piloting and further development for use with First Nations people, and two screening tools for cognitive impairment are noted for positive consideration.

Recommendations for screening tools are based on review only and evaluation was infeasible.

Short, reliable measures of cognitive ability for use in correctional facilities are needed. Such tools must be appropriate with respect to their purpose, feasible within the clinical capability of staff and sufficiently cheap to administer to allow widespread use.

Screening of prisoners for cognitive impairment allows early detection to facilitate rehabilitation and therapy. This research is at the systems level. Therefore, the authors do not purport to provide guidance for individual clinicians.

This paper aims to investigate two seminal market-scanning frameworks – the five-forces analysis and PESTEL environmental scanning tool – to assess their readiness for anticipating market-shaping acts.

Drawing on the market-shaping literature that conceptualizes markets as complex adaptive systems, this conceptual paper interrogates the underlying assumptions and “blind spots” in two seminal market-scanning frameworks. The paper showcases three illustrative vignettes in which non-industry actors catalyzed market change in ways that these market-scanning frameworks would not be able to anticipate.

Marketing strategists can be “blindsided” as seminal market-scanning frameworks have either too narrow an interpretation of market change or are too broad to anticipate specific types of market-shaping acts. The assumptions about markets that underpin these market-scanning frameworks contribute to incumbents being slow to realize market-shaping acts are taking place.

The authors extend market-scanning to include a type of managerial myopia that fails to register the socially embedded, systemic nature of complex contemporary markets. Furthermore, the paper provides an “actors-agendas-outcomes” scanning framework that offers awareness of market-shaping acts.

This paper is the first to consider market-scanning frameworks from a market-shaping perspective.

Organizations that prioritize humanistic responsibility create an environment of value for their employees as the most important stakeholders. However, despite the numerous corporate social responsibility (CSR) models and research highlighting stakeholder considerations, the long-standing “social” aspect of CSR has inhibited its humanism responsibility. In response, this study proposes to move beyond the antecedents and outcomes of CSR to explore how perceived CSR can promote its humanistic responsibility both inside and outside of organizations.

The authors followed Sendjaya et al. (2008) ’s methodology for developing and validating the perceived corporate humanistic responsibility (CHR) scale. Study 1 validated the CHR's content. Study 2 established the measure’ reliability, internal consistency, unidimensionality and discriminant validity. The authors describe each of the studies in the forthcoming sections.

This research has produced a comprehensive set of perceived CHR items for business leaders based on earlier CHR/humanism concepts. Through the deconstruction of CHR theory, the granular conceptualization provides employee-centric workplaces, healthy internal communication, holistic compensation, CSR-committed behaviors and holistic training and development, equipped to assess how their CHR fosters humanistic workplaces that encourage socially responsible behaviors. This, in turn, would have an immense impact on employee well-being that, in turn, flourishes societal well-being.

Although the perceived CHR scale's psychometric properties were confirmed using multiple tests ranging from qualitative to quantitative studies, this newly developed scale requires further investigation to explore whether internal or external relevance factors affect organizations' humanistic responsibility.

CSR is about caring for humans and the planet. The authors have unpacked what and how the human side of CSR operates for business leaders to advance their CHR practices and responsible management learning. The perceived CHR dimensions can guide business leaders to promote multidimensional humanistic behaviors inside and outside workplaces that transcend how to strengthen the humanistic responsibility behaviors of corporations to promote CHR by articulating how the “Social” aspect of CSR ought to function for employee well-being first.

This study responds to Sustainable Development Goals (SDGs) most aligned with the SDG 3 (good health and well-being) and SDG 8 (decent work and economic growth) by promoting humanistic workplaces with implications for United Nation's Principles for Responsible Management that encourages universities to educate students on humanism concepts in business management.

The originality lies in the empirical study of CHR. By incorporating the original concepts of humanism/humanistic management and CHR, the authors empirically articulate how CHR may be practically implemented as an elaborated humanistic synthesis for corporations.

The purpose of this study is to provide a unique competitive advantage to businesses in providing a wide range of products to prospective customers. To the best of the author’s knowledge, there is no study to discuss the impact of customer-centric retailing on total supply chain profit under price competition between organized and unorganized retailers.

This paper considers a supply chain comprising of organized and unorganized retailers and a single manufacturer. This paper proposes three mathematical models considering a customer-centric approach in a competitive environment. Stackelberg game is used to examine how members of the chain interact, and Nash equilibrium was used to find optimal strategies for players under different customer-centric approaches.

The results show that the total supply chain profit is higher when both organized and unorganized retailers use a customer-centric approach independently instead of collaborating process. The result, in addition, establishes that when the dissatisfying cost exceeds a certain threshold (1.5), the total profit is higher for the organized customer-centric effort model compared to the other two models.

The main contribution of the study is to examine the effect of customer-centric retailing, considering dissatisfying costs on supply chains profit and individual decision-making under price competition between organized retailers and unorganized retailers. The authors developed different mathematical models in the different customer-centric approach.

The aim of this study is to examine the relationships between taking charge, bootlegging innovation and innovative job performance, and to explore the moderating roles of felt responsibility for constructive change (FRCC) and creative self-efficacy (CSE).

Data for this research was collected from 503 employees working in a chain company. Through a longitudinal study design, a three-wave survey with 397 valid data provided support for the proposed theoretical model.

The results maintain a positive association between taking charge, bootlegging innovation and innovative job performance, indicating the mediating effect of bootlegging innovation. Additionally, both the FRCC and CSE facilitate the indirect effect of taking charge on innovative job performance through bootlegging innovation. Furthermore, the integrated moderated mediation model analysis suggested that FRCC is more vital in improving employees' innovative job performance.

This research aims to break the black box between taking charge and innovative job performance, which has been relatively unexplored. Drawing from self-determination theory (SDT) and the proactive motivation model, the authors verify the bridge-building role of bootlegging innovation and the dual-facilitating effects of FRCC and CSE while employees conduct taking charge. This study’s results provide new insight for managers to foster, encourage and support employees' proactive behavior.

This study aims to propose the reuse of PA12 (powder) in another AM process, binder jettiinng, which is less sensitive to the chemical and mechanical degradation of the powder after multiple cycles in the laser system.

The experimental process for evaluating the reuse of SLS powders in a subsequent binder jetting process consists of four phases: powder characterization, bonding analysis, mixture testing and mixture characteristics. Analyses were carried out using techniques such as Fourier Transform Infrared Spectroscopy, scanning electron microscopy, thermogravimetric analysis and stress–strain tests for tension and compression. The surface roughness, color, hardness and density of the new mixture were also determined to find physical characteristics. A Taguchi design L8 was used to search for a mixture with the best mechanical strength.

The results indicated that the integration of waste powder PA12 with calcium sulfate hemihydrate (CSH) generates appropriate particle distribution with rounded particles of PA12 that improve powder flowability. The micropores observed with less than 60 µm, facilitated binder and infiltrant penetration on 3D parts. The 60/40 (CSH-PA12) mixture with epoxy resin postprocessing was found to be the best-bonded mixture in mechanical testing, rugosity and hardness results. The new CSH-PA12 mixture resulted lighter and stronger than the CSH powder commonly used in binder jetting technology.

This study adds value to the polymer powder bed fusion process by using its waste in a circular process. The novel reuse of PA12 waste in an established process was achieved in an accessible and economical manner.
