The paper reports on research into effective leadership interventions. The findings and conclusions are derived from 12 diverse vocational education and training (VET) sites around Australia. Data are from 44 written survey and interview responses and five focus groups yielding a total of 64 respondents. The main finding is a four‐stage cycle of effective leadership interventions and is demonstrated through a case of enabling leadership. The study incorporates context‐dependent profiles of different leaders’ attributes at each of the four stages of the leadership intervention cycle. The research generates new theory and knowledge in an area of leadership research. That is, it is found that the traits and attributes of individual leaders are necessary but not sufficient to explain how to achieve effective and enabling leadership.

There is growing agreement that one of the primary drivers, if not the key driver of long‐term organizational effectiveness, is the ability of an organization to learn effectively. If this is the case, an organization committed to learning effectively must align itself to value and reward learning to create behaviour that results in a culture of learning. This paper provides the framework for a new approach based on rewarding six principles of effective learning.

Cyclic phase change involves the successive freezing and melting of a region driven by a boundary temperature that cycles above and below the solid/liquid phase change temperature. In this paper, a recently proposed fixed grid phase change enthalpy method is modified and applied to cyclic solid/liquid phase change problems. The basic approach is demonstrated on application to a one‐dimensional, heat conduction controlled phase change. Then the method is used to investigate a cyclic phase change problem that involves fluid flow. The interaction of the melting and freezing with the phase change leads to some interesting predictions for the location and shape of the solid/liquid interface. The results also indicate that melting cycles are more effective than freezing cycles.

This research aims to conduct an exploratory analysis into current industrial reverse logistics practice in business‐to‐business (B2B) and business‐to‐customer relationships (B2C), and determine the financial and operational impact of customer non‐compliance in returning distribution equipment back to their source.

The analysis was conducted over multiple industry sectors using qualitative research techniques. The research sample included seven industry sectors, providing a response rate of 72 per cent (53 sources approached). The focus was on both B2B and B2C relationships to determine similarities and differences in financial and operational repercussions.

The research findings indicate that the efficacy of the reverse logistics system can be undermined by lack of customer compliance, with losses of up to £140 million (B2B).

In both B2B and B2C relationships, there is evidence of suppliers suffering financial loss due to customer non‐compliance. Due to the small scale of the analysis and the breadth of the industry sectors investigated, these results are not generalisable, but do indicate that this is an area, which could undermine supply chain effectiveness.

Non‐compliance of this nature carries a direct and highly applicable cost for manufacturers and distributors in the practitioner arena. Suppliers within industry need to acknowledge this issue and manage their reverse logistics more effectively.

This paper adopts an innovative focus on an understated feature of the reverse logistics cycle, i.e. the recycling of distribution equipment used to transport outbound and returned products. The paper identifies a range of options, which practitioners can use as guidance when managing the returns system.

While the transference of charge is an essential aspect of every capacitance sensor, a relatively new form of sensor makes overt use of the principle of charge conservation first deduced by Watson in the 1740s. Updated to use a microcontroller, mosfet switches, fet‐input opamps and band gap references, the principle of charge transference can be used to create an extremely sensitive and stable device with unique properties that transcend those of more pedestrian capacitance sensors. Also known as “QT” sensors, charge transfer sensors can have a dynamic range spanning many decades with noise floors in the sub‐femtofarad regime, allowing differential resolutions of mere fractions of a femtofarad. Such sensors are proving to have unique applications considered heretofore impossible, while also proving themselves as replacements for much more expensive sensing systems using photoelectric, acoustic, RF, and optical imaging techniques.

The most common reaction to an acute physical illness is anxiety, which may be followed by depression. In patients with chronic diseases, the prevalence of anxiety disorders and depression is almost twice as high as in other diseases. This study aims to extract prominent components in the design of treatment spaces on reducing hospitalized patients’ depression from both experts and patients/users’ point of views. A final model is also presented based on the findings.

This research used an exploratory mixed method. The effective components were extracted through the administration of two Likert-scale researcher-made questionnaires in two phases. Q factor analysis was conducted to reach the components. A total of 205 patients were admitted to Namazi Hospital in Shiraz, and 20 architecture and psychology experts participated in the survey. Final modeling of the data was done through path analysis.

Six factors were found to be effective by experts in reducing depression in therapeutic spaces: nature-oriented space, targeted social space, diverse space, visual comfort, logical process and safe space. On the part of patients, seven components were deemed to be effective: visual perception, naturalism, functionalism, physical security, logical process, psychological safety and diversity. Also, four main cycles were extracted from the final model with the direct effect of diversity and the other five cycles were mediated by naturalism.

A total of 15 interviews with architects and psychologists, who were available at the time of the study, were conducted in January 2018. The only general question during interviews was “In your opinion, what factors are effective in reducing the level of depression of patients in the design of treatment spaces?” This may have limited the range of factors that could be surveyed in the study. After collecting the effective factors from the aforementioned expert’s points of view, the questionnaire of experts was designed (Appendix). The expert questionnaires were distributed and edited in two stages in January 2019 among 20 architect experts who were available at the time of the study. The one-year interval between designing and administering the questionnaires occurred because of the limitations posed by the COVID-19 pandemic situation. However, the interval did not pose methodological obstacles for the study.

Evidence-based investigation of the effectiveness of proper design components of therapeutic spaces in reducing the symptoms of patients with chronic secondary depression has received little attention in the literature. Using a “conceptual model,” the present study brought the issue into its focus so as to find effective components in the design of treatment spaces that can alleviate depression symptoms in chronically hospitalized patients.

The essential investments in new product development (NPD) made by industrial companies entail effective management of NPD activities. In this context, performance measurement is one of the means that can be employed in the pursuit of effectiveness.

An understanding of effective problem solving is essential for everyone involved in development teams. For most development projects, the design‐build‐test cycle is the fundamental building block of effective problem solving. Examines the design‐build‐test cycle and describes alternative modes of problem solving and their implications for organizational skills and capabilities. Examines how superior capabilities at conducting the cycle can be used to make dramatic improvements in individual product development efforts. Concludes by considering how a firm can leverage the problem‐solving ability into a competitive advantage.

This study purposes to study the influence of artificial freezing on the liquefaction characteristics of Nanjing sand, as well as its mechanism.

was studied through dynamic triaxial tests by means of the GDS dynamic triaxial system on Nanjing sand extensively discovered in the middle and lower reaches of the Yangtze River under seismic load and metro train vibration load, respectively, and potential hazards of the two loads to the freezing construction of Nanjing sand were also identified in the tests.

The results show that under both seismic load and metro train vibration load, freeze-thaw cycles will significantly reduce the stiffness and liquefaction resistance of Nanjing sand, especially in the first freeze-thaw cycle; the more freeze-thaw cycles, the worse structural behaviors of silty-fine sand, and the easier to liquefy; freeze-thaw cycles will increase the sensitivity of Nanjing sand's dynamic pore pressure to dynamic load response; the lower the freezing temperature and the effective confining pressure, the worse the liquefaction resistance of Nanjing sand after freeze-thaw cycles; compared to the metro train vibration load, the seismic load in Nanjing is potentially less dangerous to freezing construction of Nanjing sand.

The research results are helpful to the construction of the artificial ground freezing of the subway crossing passage in the lower reaches of the Yangtze River and to ensure the construction safety of the subway tunnel and its crossing passage.
