Abstract
Purpose
The purpose of this paper is to explore the qualitative relationship between cannabis and the most commonly used antidepressant drugs known as selective serotonin reuptake inhibitor (SSRIs) through the narratives of depressed individuals who have used both drugs at one point during their lifetime. Despite their prevalence, depression, cannabis use, and SSRI use have not been previously studied together through the perspective of those who have experienced them. Using a exploratory approach, this paper investigates and compares the user experiences of these drugs.
Design/methodology/approach
Semi-structured interviews were conducted involving participants who were between the ages of 16–59 in the UK and have used both SSRIs and cannabis either simultaneously or at any point in their lives. Five interviews were conducted either via telephone or in person, and the method of analysis was an inductive approach which was inspired by grounded-theory.
Findings
While the two drugs were used by participants in order to relieve symptoms of depression, they were used for very different reasons and typically at different stages of their lives. Though participants did not state that the drugs were interchangeable for improving mood, their responses indicated that these drugs were viewed as two alternatives to alleviate symptoms of depression. Participants’ relationships with their doctors also played a crucial role and affected interviewees’ decisions to use either SSRIs or cannabis, as well as perceptions of the medical industry.
Social implications
This research shows the importance of doctor and patient interactions as they were crucial influences on patients’ decisions related to drugs. Participants’ experiences with SSRI and cannabis were subjective and varied, therefore, the value of personalised treatment (which may or may not include psychotropic drugs) is highlighted. These findings can help health practitioners gain a better understanding of the rationale of depressed patients in choosing treatments and thereby improve healthcare outcomes.
Originality/value
Given that depression is stigmatised, and cannabis use is both illegal and stigmatised, this paper examines the opinions of a difficult to reach population. Previous work involving cannabis, antidepressants and mood-elevating effects is primarily written with a biochemical or medical perspective which paid more focus on the efficacy of these drugs and had less emphasis on the beliefs of the users. This paper highlights the opinions of cannabis and SSRI users regarding these two drugs specifically, which had not been previously explored.

Abstract
Purpose
This study isolates the effect of immersion on players’ learning in a virtual reality (VR)-based game about cellular biology by comparing two versions of the game with the same level of interactivityand different levels of immersion. The authors identify immersion and additional interactivity as two key affordances of VR as a learning tool. A number of research studies compare VR with two-dimensional or minimally interactive media; this study focuses on the effect of immersion as a result of the head mounted display (HMD).
Design/methodology/approach
In the game, players diagnose a cell by exploring a virtual cell and search for clues that indicate one of five possible types of cystic fibrosis. Fifty-one adults completed all aspects of the study. Players took pre and post assessments and drew pictures of cells and translation before and after the game. Players were randomly assigned to play the game with the HMD (stereoscopic view) or without the headset (non-stereoscopic view). Players were interviewed about their drawings and experiences at the end of the session.
Findings
Players in both groups improved in their knowledge of the cell environment and the process of translation. Players who experienced the immersive stereoscopic view had a more positive learning effect in the content assessment, and stronger improvement in their mental models of the process of translation between pre- and post-drawings compared to players who played the two-dimensional game.
Originality/value
This study suggests that immersion alone has a positive effect on conceptual understanding, especially in helping learners understand spatial environments and processes. These findings set the stage for a new wave of research on learning in immersive environments; research that moves beyond determining whether immersive media correlate with more learning, toward a focus on the types of learning outcomes that are best supported by immersive media.

Abstract
Possibly one of the greatest misconceptions about Chicano historiography is the view that published intellectual writings by Chicanos are of recent vintage, traceable only over several decades. This assumption is in part supported by the large and growing body of contemporary published materials by and about Chicanos, especially within the past 15 years.

Abstract
Purpose
This study aims to examine the role of support actors in promoting or hindering access to public services/spaces for migrant agricultural workers (MAWs) and to determine the factors that influence adequate support for this population.
Design/methodology/approach
Using a situational analysis methodology, the authors carried out focus groups and interviews with 40 support actors complimented by a community scan (n = 28) with public-facing support persons and a community consultation with migrant farmworkers (MFWs) (n = 235).
Findings
Two major themes were revealed: (In)access and (In)action and Blurred Lines in Service Provision. The first illustrated how support actors could both reinforce or challenge barriers for this population through tensions of “Coping or Pushing Back on Constraints” and “Need to find them first!” Justification or Preparation? Blurred lines in Service Provision encompassed organizational/staff’s behaviors and contradictions that could hinder meaningful support for MFWs revealing two key tensions: “Protection or performance?” and “Contradicting or reconciling priorities? Our findings revealed a support system for MAWs still in its infancy, contending with difficult political and economic conditions.
Social implications
Service providers can use research findings to improve supports for MAWs. For example, addressing conflicts of interests in clinical encounters and identification of farms to inform adequate outreach strategies can contribute to more effective support for MAWs.
Originality/value
This research is novel in its examination of multiple sectors as well as its inclusion of both formal and informal actors involved in supporting MAWs. Our findings have the potential to inform more comprehensive readings of the health and social care resources available to MAWs.

Abstract
Purpose
The purpose of this paper is to examine the management innovations developed and implemented by the Harvey House restaurants with specific attention to those human resource policies and procedures that were created to use what many believe to be the first large-scale use of single women working away from home, the famous Harvey Girls. A second purpose of this paper is to use bricolage theory to frame the innovations that Harvey pioneered to illustrate how the theory pertains to this entrepreneur who civilized dining in the “Wild West.”
Design/methodology/approach
This paper relies on secondary and archival sources to inform its points and rationale.
Findings
Fred Harvey applied his experience-gained knowledge to invent a system that would provide meals to railroad travelers along the Atchison, Topeka and Santa Fe railroad that were not only consistently excellent and reasonably priced but also could be served within the tight time limits of train stops for fuel and water. The precision of his service standards was innovative and required trained and disciplined servers. To deliver the quality of service for which his company became known across the “Wild West.” Harvey invented his famous Harvey Girls.
Originality/value
Fred Harvey’s invention of the Harvey Girls represents the first large-scale employment of women and required the invention of human resource management policies, procedures and processes. This is the story of how this management innovator successfully applied entrepreneurial bricolage to bring civilized dining to the “Wild West.”

Abstract
Purpose
This paper aims to present the design of a micro-electro-mechanical system (MEMS)-based three-dimensional combined vector hydrophone tailored for unmanned underwater vehicles (UUVs). The proposed design addresses the left-right ambiguity inherent in conventional MEMS hydrophones and enhances acoustic sensing capabilities to support improved UUV performance in underwater environments.
Design/methodology/approach
A novel MEMS-based three-dimensional vector hydrophone (M3DH) is proposed, integrating a highly sensitive MEMS chip with a piezoelectric ceramic-based scalar channel. A theoretical model of the hydrophone’s packaging was developed, and its acoustic performance was analyzed through COMSOL Multiphysics 6.2 simulations. Experimental validation of the hydrophone’s sensitivity and directional characteristics was conducted in a standing wave tank.
Findings
The MEMS-based three-dimensional combined hydrophone (M3DH) achieved a triaxial vector channel sensitivity of −175.6 dB at 800 Hz (re 1 V/µPa) and a scalar channel sensitivity of −186.3 dB (0 dB = 1 V/µPa). In addition, at 500 Hz, the vector channel exhibited a distinct “8”-shaped directivity pattern, whereas the scalar channel maintained a circular omnidirectional response. The hydrophone demonstrated excellent acoustic performance in three-dimensional space, effectively providing comprehensive acoustic information for small underwater platforms.
Originality/value
This research addresses the left-right ambiguity issue in MEMS hydrophones by presenting an MEMS-based three-dimensional combined hydrophone designed for integration into UUVs, offering an innovative solution to enhance underwater acoustic sensing capabilities in small platforms.
