Jung’s Axioms: An Introduction to Jung’s “Note on Number”

This article is an introduction to C. G. Jung’s handwritten note on natural numbers (in this issue), which became the basis of Marie-Louise von Franz’s book Number and Time. I present the historical background of Jung’s note and discuss part of its content using mostly Jung’s own words.     

Military Family Advocacy in the U.S. Army: Program Service Outcomes and Family Participation

Violence in military families remains a vexing problem. Since the advent of the Global War on Terror, there is inconsistent evidence that the prevalence of family violence is increasing, particularly during and after military deployments. However, child neglect appears to increase significantly during military deployments. The military has developed family advocacy programs designed to keep families safe and intervene to reduce the deleterious effects of exposure to family violence. This is one of the first studies to examine the quality with which a family advocacy program is implemented and the degree to which families engage with the program. To conduct this study, the case files of 226 families who came in contact with the Army Family Advocacy Program (FAP) and whose cases were closed in 2013 were reviewed and coded across several implementation and service outcomes. These included involvement of qualified staff, whether or not appropriate victim and offender assessments were completed, degree of inter-agency communication, and appropriateness of referrals, among others. Soldier and family member participation in FAP and other Army-sponsored programs designed to reduce violence was also assessed. Generally speaking, the Army Family Advocacy Program was implemented with high quality, established processes and procedures for handling cases were largely followed, and FAP staff responded rapidly and thoroughly to reported abuse. However, family engagement with Army services and supports was low. Developing robust approaches to engaging families in family programming must be a high priority going forward.     

Do chimpanzees anticipate an object’s weight? A field experiment on the kinematics of hammer-lifting movements in the nut-cracking Taï chimpanzees

When humans are about to manipulate an object, our brains use visual cues to recall an internal representation to predict its weight and scale the lifting force accordingly. Such a long-term force profile, formed through repeated experiences with similar objects, has been proposed to improve manipulative performance. Skillful object manipulation is crucial for many animals, particularly those that rely on tools for foraging. However, despite enduring interest in tool use in non-human animals, there has been very little investigation of their ability to form an expectation about an object’s weight. In this study, we tested whether wild chimpanzees use long-term force profiles to anticipate the weight of a nut-cracking hammer from its size. To this end, we conducted a field experiment presenting chimpanzees with natural wooden hammers and artificially hollowed, lighter hammers of the same size and external appearance. We used calibrated videos from camera traps to extract kinematic parameters of lifting movements. We found that, when lacking previous experience, chimpanzees lifted hollowed hammers with a higher acceleration than natural hammers (overshoot effect). After using a hammer to crack open one nut, chimpanzees tuned down the lifting acceleration for the hollowed hammers, but continued lifting natural hammers with the same acceleration. Our results show that chimpanzees anticipate the weight of an object using long-term force profiles and suggest that, similarly to humans, they use internal representations of weight to plan their lifting movements.     

The Moscow Council of 1917–1918

Following a period of decline beginning in the early eighteenth century, the Orthodox Church in Russia held a general council in Moscow from August 1917 to September 1918. More than 500 clergy and laity met, prayed and discussed numerous issues relating to the church’s life and witness. The Moscow Council was prompted by various trends of renewal which were growing ever stronger among the clergy and laity. Political circumstances at the time also made the Council possible: a preparatory preconciliar process was initiated in 1905, in parallel with the first revolution against Emperor Nicholas II, and the Council itself was convened in 1917, in parallel with the establishment of a Provisional Government. However, it was precisely such political events which led to the premature interruption of the Council. The main items on the Council’s agenda were linked to the reformation of church structures and the implementation of conciliar provisions at every level of church life: parish, deanery, diocese and autocephalous church. Special attention was given to the renewal of the pastoral ministries of priests and bishops, and to that of committed laity. In a way, the Moscow Council was a kind of ‘first encounter’ of Orthodoxy with contemporary societies, secularised or on the road to secularisation. Its legacy is therefore of great interest to all Christianity today. This article aims to analyse the Council and the main decisions made, in the light of ecclesiology, and to provide a primary bibliography at the end of the text.     

Group therapy program development: clinician-administrator collaboration in new practice settings

Despite being practiced widely and applied to many conditions, group therapy is underutilized in some segments of the market. One important reason for its underuse is the lack of a model for group program development. Program development requires an integrated effort involving many disciplines. Effective collaboration between clinicians and administrators is an essential but underappreciated component in the development of group programs in independent practice associations.     

Motivating signage prompts safety belt use among drivers exiting senior communities

Senior drivers are vulnerable to automobile crashes and subsequent injury and death. Safety belts reduce health risks associated with auto crashes. Therefore, it is important to encourage senior drivers to wear safety belts while driving. Using an AB design, replicated five times, we evaluated the short- and long-term effects of a sign with the message "BUCKLE UP, STAY SAFE" attached to a stop sign at the exits of five different senior communities. Safety belt use was stable during two pretreatment assessments averaged across the five sites and 250 drivers (72% and 68% usage), but significantly increased following installation of these signs (94% usage). Six months after installation of the signs, the effect persisted (88% usage). Use of such signs may be a cost-effective way of promoting safety belt use.     

Method choice, intent, and gender in completed suicide

Women who commit suicide use less violent methods, such as drugs and carbon monoxide poisoning, than do men, who more often use violent methods such as guns and hanging. Theories that attempt to explain this finding focus on gender differences in suicidal intent, socialization, emotions, interpersonal relationships, orientation and access to methods, and neurobiological factors. Data from a psychological autopsy study were used to test the theory that women who commit suicide use less violent means because they are less intent on dying. Although women were significantly less likely to use a violent method than men, there was no difference in the lethality of their suicidal intent.     

Perinatal maternal undernutrition programs the offspring hypothalamo-pituitary-adrenal (HPA) axis

There is now compelling evidence, coming both from animal and human studies that an early exposure to undernutrition is frequently associated with low birth weight and programs HPA axis alterations throughout the lifespan. Although animal models have reported conflicting findings arising from differences in experimental paradigms and species, they have clearly demonstrated that such programming not only affects the brain but also the pituitary corticotrophs and the adrenal cortex. In fetuses, maternal undernutrition reduces HPA axis function and implicates a reduction of placental 11beta-HSD2 activity and a greater transplacental transfer of glucocorticoids (GRs). In young adults, usually only fine HPA axis alterations were observed, whereas in older ones, maternal undernutrition was frequently associated with chronic hyperactivity of this neuroendocrine axis. In humans, evidence of HPA axis dysregulation in people who were small at birth has recently emerged. Thus, we suggest that such alterations in adults may be implicated in the aetiology of several disorders related to the metabolic syndrome as well as to immune or inflammatory diseases. To reverse such programming, recent experimental reports have shown that postnatal environmental interventions, dietary modifications and the use of agents modulating the epigenomic state could partly restore physiological functions and thus open new therapeutic strategies.     

Action planning in young children's tool use

Tool use consists of at least two coupled phases of activities, involving multi-step problem solving. It therefore provides an interesting window on the development of planning in goal-directed behavior. This study investigated 2-year-olds' and 3-year-olds' hand use in picking up and subsequently using a tool for displacing a target-object towards a specified goal location. The children had to use a stick (Experiment 1; N = 41 in total) or a cane (hooked stick) that was lying in varying starting orientations (Experiment 2; N = 32 in total). Age differences were found in the way goal-related information in combination with tool-related information influenced the choice of which hand to use in different phases of the task. A view on action planning is developed as a dynamic action-selection process for which actions to take. This process integrates factors that are internal to the child's action system (e.g. motor preferences and dexterity) with external (i.e. sensory) sources of information.
