This paper aims to study the impacts of groundwater seepage on artificial freezing process of gravel strata, the temperature field characteristics of the strata, and the strata process, closure time and thickness evolution mechanism of the frozen wall.

In this paper several laboratory model tests were conducted, considering different groundwater seepage rate.

The results show that there is a significant coupling effect between the cold diffusion of artificial freezing pipes and groundwater seepage; when there is no seepage, temperature fields upstream and downstream of the gravel strata are symmetrically distributed, and the thickness of the frozen soil column/frozen wall is consistent during artificial freezing; groundwater seepage causes significant asymmetry in the temperature fields upstream and downstream of the gravel strata, and the greater the seepage rate, the more obvious the asymmetry; the frozen wall closure time increases linearly with the increase in the groundwater seepage rate, and specifically, the time length under seepage rate of 5.00 m d⁻¹ is 3.2 times longer than that under no seepage; due to the erosion from groundwater seepage, the thickness of the upstream frozen wall decreases linearly with the seepage velocity, while that of the downstream frozen wall increases linearly, resulting in a saddle-shaped frozen wall.

The research results are beneficial to the optimum design and risk control of artificial freezing process in gravel strata.

Investigating technical terms of vehicle spare parts used in the mechanics' jargon in Saudi Arabic (SA) and Yemeni Arabic (YA) has received scant attention. The current study, therefore, is an attempt to shed some light on the topic. The aim is to identify the strategies used for creating equivalents in vehicle spare parts vocabulary and to pinpoint the most salient variations between the two dialects in this jargon.

More than 250 terms of vehicle spare parts were collected and analyzed qualitatively. Each list contains nearly 125 items. They were gathered from two main resources: semi-structured interviews with vehicle mechanics, and written lists from spare parts dealers in both countries.

Three main strategies are found at work: lexical borrowing (from English and French), metaphor and loan translation. Direct borrowing is the most influential strategy where loanwords represent nearly one-third of the data, the majority of which is from English. Metaphorical extensions and literal translations also have an important role to play in the process of spare part naming. While the two dialects share common practices in terms of literal translation, they are characterized by many differences with regard to lexical borrowing and metaphors.

The study approaches an under-researched topic that is related to the mechanic's jargon in Arabic and leaves the door open for further research. The findings of this study may be used as guidelines for Arabic academies and those who are concerned with translating and studying technical terms in the field of mechanical engineering.

This paper aims to show agential realism as the basis for a pertinent framework with regard to the entwined, on-going and interpretative aspects of knowledge.

The knowledge flow phenomenon in the form of entanglement and agential “cuts” within the workplace is studied and described across a phenomenological ethnographic case study of two workgroups within an aircraft engine manufacturing context.

The boundary construction phenomenon is a key process helping us to depict knowledge entanglement (tacit and explicit) across dialogue and non-verbal actions. Dialogue brings forth the aspect of knowledge as interpretations or “cuts.” A phenomenological analysis allows us to identify and describe various levels of tacit–explicit knowledge entanglement depending on the mode of coping at hand. Also highlighted was the importance of heuristics carried out by knowledge experts, often in the form of abduction (i.e. leading to rules of thumb).

It is acknowledged that the relatively narrow context of the empirical work limits the ability to generalize the findings and arguments. As such, additional work is required to investigate the validity of the findings across a wider spectrum of workgroup contexts.

Agential realism allows for the analysis of organizations as a world of practice and actions, whereby long-established categories can be requestioned and challenged with the aim of sharing the full richness and benefit of embodied knowledge between human actors.

Ethnographic descriptions of the entwined nature of tacit and explicit knowledge, the embodied and activity-based dimension of knowledge and learning, as well as the characteristic of knowledge as possession, correspond well to an agential realist concept of phenomenon, entanglement and cuts. Furthermore, agential realism offers the opportunity to view the workplace as individuals (or groups) who act out embodied tacit-explicit knowledge in conjunction with non-human entities (such as objects, as well as communication and information technologies), with the latter acting as enhancers of knowledge creation and sharing.

This paper aims to present reflections on the frustrations of working in the modern business office setting.

This is a fictional poem.

The poem reveals that the accumulation of relatively minor irritants, distractions and frustrations can have a significantly deleterious effect on the mental condition of some sensitive office workers.

The paper presents warning signs for the potential implications for occupational health and safety of the culture and working conditions prevalent in many office environments in the twenty‐first century.

The paper presents a poet's perspective on modern office working conditions.

The effect of the tube wall heat conduction on the natural convection in a tilted long cylindrical envelope with constant, but different temperature of the two ends and an adiabatic outer surface was numerically investigated. The envelope is supposed to be a simplified model for the pulse tube in a pulse tube refrigerator when the pulse tube is positioned at different orientations. It is found that the cylindrical envelope lateral wall heat conduction can enhance the heat transfer from the hot end to the cold end, not only because of the increase in pure heat conduction in the wall, but more importantly, also the intensification of the natural convection within the enclosure. This enhancement is resulted from the big temperature difference between the tube wall and the adjacent fluid near the hot and cold ends. Adoption of low thermal conductivity tube can effectively reduce such additional heat transfers from hot to cold end, thus reducing the loss of cooling capacity for the pulse tube refrigerator.

Purpose – The purpose of this chapter is to retell the narratives of a preservice teacher and a teacher educator as they lived a story of critical literacy and curriculum-making as a curriculum of lives.

Approach – The chapter presents a year-long narrative inquiry centered on the revisioning of curriculum for an undergraduate literacy course for preservice teachers.

Findings – The researcher broadened her understanding of teacher and teacher educators as curriculum makers to include preservice teachers as curriculum makers. As preservice teachers in the literacy course were invited to reflect on their own literacy backgrounds, several crucial narratives emerged that shaped new understandings for the researcher/teacher educator and drew her into her own curriculum-making with moral purpose. One preservice teacher began a journey of narrative authority and curriculum-making as a curriculum of lives in a subsequent field experience, even through the mire of political pressure in schools.

Research implications – The preservice teacher's retelling featured children who discovered newfound understandings of social justice through literary ways of knowing and critical literacy events. She developed new understandings of how to help public school students value and define their literacies and their life events, all of which folded back into the undergraduate literacy course.

Value – Teacher educators can be encouraged to walk in relationship with their preservice teachers, valuing human experiences and lives as curriculum rather than relenting to top-down, politically driven, outside curriculum.

To improve the operational management benefits of large-scale sports venues, the literature data method, questionnaire survey method, and comparative analysis method were used to study the planning and management of large-scale sports stadiums in China. From the macro external environment, the micro external environment and the internal management of the venue, the opportunities and challenges of China's large stadiums were analyzed. Corresponding countermeasures to improve the efficiency of venue operation management were proposed. The results show that the proportion of business structure of large-scale sports stadiums in China was unreasonable, and the ontology management was in a polarized development trend. The venue utilization rate was generally low. In addition, the operational management benefits of large-scale sports stadiums in China were affected by the micro-external environment and the internal conditions of the venues. Therefore, this research has important reference significance for the operation and management of stadiums.

Approximately 50 years ago, William Westley’s (1953) pioneering study of police officers brought to the forefront the special characteristics of police work. The present research raises the question: how far have thepolice come since Westley? Using focus group interviews and surveys collected from alarge Southwest police department, the study examines the situational role context of physical force. In doing so, it provides an explanation of physical force today, compared to explanations offered by Westley. The current research examines whether officer use of physical force and its severity are determined by the situation. The results confirm this hypothesis by suggesting that physical force is determined situationally, according to low‐order excessive force and high‐order violent force. As a way of understanding the lack of change in attitudes and practice of physical force, a possible explanation is the patrol culture.

The purpose of this study is to investigate into the perception of new public sector management (NPM) and service delivery among senior officers of the Mauritian public sector in the context of reforms. Although improved service delivery is one of the salient outcomes of successful reforms of NPM, many governments in the world have not been able to fulfil this promise. While few extant research probe into the factors affecting service delivery, mostly from the customer’s perspective, this study probes into how senior public officers themselves perceive service delivery as part of their duty in government.

The qualitative stance was adopted for this study. Interviews were conducted with 23 senior public officers having on average 20 years of service in the Mauritian public sector. Data obtained was transcribed and coded under themes, sub-themes and emergent themes. These were then analysed in the light of the literature review conducted.

The findings of this study revealed that NPM was being practiced and service delivery was an imbedded factor among senior public sector officers of the Mauritian public sector. Among other factors, officers interviewed were of the opinion that serving the public was a legitimate part of their job, view that they had agreed to serve the government of Mauritius. Such a finding proves to be very encouraging for the Mauritian Government, still struggling to achieve reforms or NPM doctrines.

This study contributes to the scant literature on NPM and service delivery in small island developing states. It explores the perception of experienced senior officers about the practice of NPM and the state of service delivery.

This study elucidates how senior public servants themselves perceive service delivery and can, thus, serve as an example of public sector best practices in small island developing states.

While most studies with respect to public sector reforms concentrate on developed countries, this study takes place in the small island state of Mauritius. More so, the perception of public servants themselves have been explored in the context of service delivery improvement and reforms, contrary to other studies which concentrate of the customers’ perceptions.
