Large-eddy simulations are analysed to determine the influence of suspended canopies, such as those formed in macroalgal farms, on ocean mixed layer (OML) deepening and internal wave generation. In the absence of a canopy, we show that Langmuir turbulence, when compared with wind-driven shear turbulence, results in a deeper OML and more pronounced internal waves beneath the OML. Subsequently, we examine simulations with suspended canopies of varying densities located in the OML, in the presence of a background geostrophic current. Intensified turbulence occurs in the shear layer at the canopy’s bottom edge, arising from the interaction between the geostrophic current and canopy drag. Structures resembling Kelvin–Helmholtz (KH) instability emerge as the canopy shear layer interacts with the underlying stratification, radiating internal waves beneath the OML. Both intensified turbulence and lower-frequency motions associated with KH-type structures are critical factors in enhancing mixing. Consequently, the OML depth increases by up to a factor of two compared with cases without a canopy. Denser canopies and stronger geostrophic currents lead to more pronounced KH-type structures and internal waves, stronger turbulence and greater OML deepening. Additionally, vertical nutrient transport is enhanced as the OML deepens due to the presence of the canopy. Considering that the canopy density investigated in this study closely represents offshore macroalgal farms, these findings suggest a mechanism for passive nutrient entrainment conducive to sustainable farming. Overall, this study reveals the intricate interactions between the suspended canopy, turbulent mixing and stratification, underscoring their importance in reshaping OML characteristics.
Lately, my students have been asking: “Why should we be here, when there are people suffering out there?” Evidently, they are asking about the public value of higher education. But they are also asking old questions, some of the oldest that human beings have seen fit to ask. Versions of these questions appear in all scriptural traditions, in ancient and modern philosophical works, in stories and novels and songs. They are questions at the core of what we call “the humanities.” Part of why we study the humanities – and why we must – is to get help in asking, articulating, and trying to answer such questions. There aren’t single right answers to any of those questions. Each of us must work answers out for ourselves. But we can work out better answers for ourselves if we spend time in the company of others who take those questions seriously. This is not just an individual task; it’s a collective task of great public import. In this short piece, I defend the idea of the public humanities on these terms.
Psychiatric illnesses are common in the perinatal period and many women are treated with psychotropic medications. Prescribing psychotropic medications often raises concern among patients and clinicians, because of a lack of information and no license to prescribe during pregnancy. This project aimed to evaluate the interventions offered in a perinatal clinic against the Perinatal College Centre for Quality Improvement standards. This included evaluating medications prescribed in the antenatal and postnatal periods; counselling regarding medication risks and benefits, provision of verbal and written information and psychosocial interventions.
Methods
Data of 60 patients (30 antenatal and 30 postnatal) attending perinatal outpatient clinics covering two cities in Midlands, England, consecutively from November 1st 2023 were collected from electronic clinical notes and clinic letters. Patients who did not attend their appointment were excluded.
Results
The mean age of the sample was 30.3 ± 5.2 (range 19–41). Average gestational age was 6.5 ± 2.1 months (range 2.0–9.5) for antenatal women, and average postnatal duration was 6.5 ± 5.0 months (range 0.1–22.0) at the time of review. All women had psychiatric diagnosis, except one who was discharged back to primary care. The most common diagnoses were mixed anxiety and depression (38.3%), emotionally unstable personality disorder (38.3%), and postnatal depression (20%). The majority (75.0%) were prescribed psychotropic drugs. Antidepressants were prescribed in 66.7% of antenatal and 76.7% postnatal patients; most commonly prescribed overall were sertraline (33.3%) and citalopram (23.3%). Antipsychotics were prescribed in 30.0% of antenatal and 46.7% of postnatal patients. Aripiprazole and quetiapine were most commonly prescribed in the antenatal (both 13.3%) and postnatal (both 20%) periods. A larger proportion (40.0%) of women had as required medications; promethazine (20.0% vs 30.0%), diazepam (6.7% vs 13.3%) and zopiclone (3.3% vs 13.3%) were most frequently prescribed, with figures indicating prescription rates in the ante- versus postnatal period. None of the medications were prescribed above licensed limits nor met criteria for high dose antipsychotic monitoring. Verbal and written information about medications was provided in 78.3% and 35.0% of all cases respectively. Most (65.0%) women were offered psychological therapies, and of these, 69.2% received it.
Conclusion
Most women in the perinatal period were prescribed psychotropic drugs, with higher proportions in the postnatal period. The findings suggested areas of improvement, such as offering written information, documenting the discussion of medication counselling, and to increase the psychotherapeutic support. It also suggests developing manualised educational interventions to improve information sharing with patients, and perinatal care.
This study investigates the influence of suspended kelp farms on ocean mixed layer hydrodynamics in the presence of currents and waves. We use the large eddy simulation method, where the wave effect is incorporated by solving the wave-averaged equations. Distinct Langmuir circulation patterns are generated within various suspended farm configurations, including horizontally uniform kelp blocks and spaced kelp rows. Intensified turbulence arises from the farm-generated Langmuir circulation, as opposed to the standard Langmuir turbulence observed without a farm. The creation of Langmuir circulation within the farm is attributed to two primary factors depending on farm configuration: (i) enhanced vertical shear due to kelp frond area density variability, and (ii) enhanced lateral shear due to canopy discontinuity at lateral edges of spaced rows. Both enhanced vertical and lateral shear of streamwise velocity, representing the lateral and vertical vorticity components, respectively, can be tilted into downstream vorticity to create Langmuir circulation. This vorticity tilting is driven by the Craik–Leibovich vortex force associated with the Stokes drift of surface gravity waves. In addition to the farm-generated Langmuir turbulence, canopy shear layer turbulence is created at the farm bottom edge due to drag discontinuity. The intensity of different types of turbulence depends on both kelp frond area density and the geometric configuration of the farm. The farm-generated turbulence has substantial consequences for nutrient supply and kelp growth. These findings also underscore the significance of the presence of obstacle structures in modifying ocean mixed layer characteristics.
As policy emerges from the interplay of economic, political, and social forces, determining whether research has made a difference to policy choices on aging issues is extremely difficult. Such a determination demands attention to the "black box" of the policy process, and the setting within which policy ultimately operates. This paper presents a Seniors' Independence Research Program as a case illustration of how research has made a difference to policy choices by stakeholder involvement throughout the research process. Strategies ensure stakeholder collaboration in policy issue search, filtration, definition, and prioritization; involvement in the design, implementation, and evaluation of health services models; and participation in achieving long-term evidence-based changes in policy and practice.
A unique and accessible guide to contemporary psychodynamic therapy and its applications. Introduced with a foreword by Nancy McWilliams, an author line-up of experienced educators guide the reader through the breadth of psychodynamic concepts in a digestible and engaging way. The key applications of psychodynamic psychotherapy to a range of presentations are explored, including anxiety, depression, problematic narcissism as well as the dynamics of 'borderline' states. Specific chapters cover the dynamics of anger and aggression, and working with people experiencing homelessness. A valuable resource for novice and experienced therapists, presenting a clear, comprehensive review of contemporary psychodynamic theory and clinical practice. Highly relevant for general clinicians, third-sector staff and therapists alike, the authors also examine staff-client dynamics and the development of psychologically-informed services underpinned by reflective practice. Part of the Cambridge Guides to the Psychological Therapies series, offering all the latest scientifically rigorous, and practical information on a range of key, evidence-based psychological interventions for clinicians.
This chapter provides an introduction to psychodynamic theory as applied to settings outwith the specialist psychotherapy clinic, paving the way for the chapters that follow in Part 4. An individual’s internal world affects how they relate to others. Others may be unconsciously invited into playing old roles that are familiar to the individual (such as rejecting, not listening, criticising), even though these roles bring difficulty and distress to both sides. This chapter explores how these powerful but sometimes ‘invisible’ interpersonal dynamics may play out between service users and staff in settings where the human relationship is at the fore (such as schools, social service agencies, and hospitals). We also discuss splitting within a clinical team and other system dynamics. In circumstances where services and professionals can sustain a good-enough therapeutic environment in the face of unconscious invitations to repeat a problematic relationship, trust may develop between service user and service and many people are able to discover new ways of forming relationships. This depends partly on the capacities and current state of the person using a service, but also, crucially, on the capacity of the professionals and services to observe and be reflective about both sides of the relationship.
This chapter explores the complex area of working with patients who experience relational difficulties and who may function predominantly at a borderline level of psychological organization. These patients are influenced by early traumatic experiences, which can shape the therapeutic encounter. They often don’t have the kind of early experience that enables them to develop the capacity to recognise feelings and to know that they are not dangerous, that they are bearable, and will pass. Acts of self-harm are frequently a response to manage unbearable feelings. These and the experience of suicidal thoughts can be understood as a wish to get rid of these feelings. The nature of self-harm and what it evokes in the clinician are discussed. Individuals with these difficulties have often experienced a lack of a consistent and containing other and can enter crisis in response to experiences of rejection or threats of abandonment. This is important both during therapy but particularly when ending the therapy. If we understand what underpins the relational difficulties that these patients have, we can take them into account in the therapeutic work. Some adaptations of technique when working with patients with borderline level difficulties are considered.
This chapter provides a brief introduction to the relational dynamics underlying ‘multiple exclusion homelessness’ and an approach to working in this area. Adults experiencing multiple exclusion homelessness have often, during their developmental years, experienced multiple homes, disrupted attachments, un-forecasted endings, multiple and short-lived figures of support – all experiences that can lead a person to develop an understandable anxiety about trusting anyone to remain stable in their life. These dynamics may inadvertently be recreated in the person’s adult life through the impermanency of different organisations they are involved with. Multiple exclusion homelessness can be understood as a late emerging symptom of underlying difficulties in someone’s relationships with care. A psychologically informed approach for staff working in the homeless sector is outlined. The staff-service user relationship, while often viewed as important within mainstream services, is commonly seen as a vehicle through which treatments can be completed rather than as the treatment itself. By contrast, a psychologically informed service for people experiencing multiple exclusion homelessness understands that the reverse is often more accurate: that the tasks and activities are really just the vehicle through which a relationship can develop that carries the possibility of developing a sense of safety, trust, and continuity.
There are many ways of becoming depressed. In this chapter we highlight common developmental themes and therapeutic situations amongst people who experience depressing/depressed states. In particular, we expand on two common clinical constellations in some detail: the first a pattern to do with dynamics of loss and abandonment; and the second a tendency to harsh self-criticism, which leads to a devaluing of oneself and others. We use the phrase ‘depressing/depressed’ state to capture the dynamic nature of depression, as opposed to conceptualising depression as a passive state of affairs when someone ‘just is’ depressed. From a psychodynamic view, this is an active and dynamic situation, where an aspect of someone’s internal world is depressing in some way to that person, leaving them feeling depressed. This chapter approaches the external manifestations of depressing/depressed states not as a discrete ‘disorder’, but more as a ‘basic emotional response’ that signals that something is amiss in an individual’s world which requires attending to and addressing.
Psychoanalytic work is always under threat of degradation; for example, understanding is replaced by education, or subtle pressure on the patient to function in a different way (that is getting him to think or behave differently, give up his symptoms etc.). One of the most important locations of this degradation of growth-promoting thought takes place at the site of the transmission of knowledge from one generation to the next. The supervisee is on the one hand being taught and at the same time needs to discover for herself a way of doing things that truly belongs to her. This chapter discusses these tensions giving illustrative examples suggesting that supervising must join the list of the impossible professions.
A psychodynamic approach to anxiety is not disorder specific; anxiety can and usually is present to varying degrees in all patients that are seen for psychodynamic psychotherapy. This chapter aims to shed some light on some psychodynamic approaches to thinking about anxieties. Using theory and clinical examples we think about how difficulties in containing processes between caregiver and infant early in the infant’s life may predispose to the persistence of archaic anxieties. We go on to explore the nature of separation and loss in relation to anxiety and finally, we reflect on how internal conflict and the role of a critical internal object can bring about anxiety. The clinical examples illustrate how wider variation in anxieties may present in therapy and the last section focuses on how the therapist may experience and respond to these different anxieties.
This chapter is a summary of psychodynamic psychotherapy and includes elements of the theory and technique of psychodynamic psychotherapy. It starts with a brief description of what it is and drawing on work by Blagys and Hilsenroth. Seven key features of psychodynamic psychotherapy are described. There is a very brief outline of the various schools of psychotherapy in order to orient the reader. This is followed by brief practical sections explaining the differences between brief and long-term therapy, and between open-ended and closed therapy. Practicalities involved in combining therapy with psychotropic medication are discussed.
This chapter starts by considering anger and the various routes to this feeling. We discuss how anger can be a desperate call to be attended to and a powerful invitation to neglect. We then discuss aggression and violence, including the potential role of shame and humiliation. At times, violence may accompany a process of an individual projecting unwanted, intolerable, or overwhelming feelings into another person. At other times, violence may be understood more in the context of fighting a perceived danger. We take inclusive approach to contemporary theory, noting that more than one approach may be useful when trying to understand a person’s actions. We touch on wider societal responses to violence, acknowledging that this is a potentially divisive area associated with strong feelings. The dynamics of anger, aggression, and violence are not necessarily straightforward to make sense of, and it is easy for any of us to inadvertently become drawn into responses that may make a situation worse. Conversely, with an awareness of key dynamics and time to reflect on these, professionals and teams can find an understanding of angry, aggressive, or violent encounters, which is a prerequisite for safe practice, working matters through, and resisting harms.
