Xi Zhu, Douglas R Wholey
OBJECTIVE: To examine how expertise redundancy and transactive memory (TM) in interdisciplinary care teams (ICTs) are related to team performance. DATA SOURCES/STUDY SETTING: Survey and administrative data were collected from 26 interdisciplinary mental health teams. STUDY DESIGN: The study used a longitudinal, observational design. Independent variables were measured at baseline, 6, and 12 months: expertise redundancy (the extent to which team members possess highly overlapping knowledge), TM accuracy (the extent to which team members accurately recognize experts in relevant knowledge domains), and TM consensus (the extent to which team members agree on who is expert in which knowledge domain)...

There is a growing trend in traumatic brain injury (TBI) rehabilitation, and research, to focus on the processes of adaptation following the injury. Resiliency is an umbrella term describing the range of personal protective factors, environmental supports and resources, as well as self-regulatory processes, engaged in response to adversity. An affective, cognitive, and behavioural self-regulatory process model of resiliency in the workplace was adapted to suit the TBI context. Through a narrative review of the literature pertaining to brain injury rehabilitation, participation, and resilience, we substantiated the model, and explained how resiliency can frame research on life experiences following the injury...

While we often engage in conversational reminiscing with loved ones, the effects of these conversations on our memory performance remain poorly understood. On the one hand, Wegner's transactive memory theory predicts that intimate groups experience benefits from remembering together. On the other hand, research on collaborative recall has shown costs of shared remembering in groups of strangers-at least in terms of number of items recalled-and even in intimate groups there is heterogeneity in outcomes. In the current research, we studied the effects of particular communicative features in determining the outcomes of collaborative recall in intimate groups...

It is difficult to predict whether newly learned information will be retrievable in the future. A biomarker of long-lasting learning, capable of predicting an individual's future ability to retrieve a particular memory, could positively influence teaching and educational methods. Event-related potentials (ERPs) were investigated as a potential biomarker of long-lasting learning. Prior ERP studies have supported a dual-process model of recognition memory that categorizes recollection and familiarity as distinct memorial processes with distinct ERP correlates...

The neurodegenerative disorder Alzheimer's disease is characterised by the formation of β-amyloid plaques and neurofibrillary tangles in the brain parenchyma, which cause synapse and neuronal loss. This leads to clinical symptoms, such as progressive memory deficits. Clinically, these pathological changes can be detected in the cerebrospinal fluid and with brain imaging, although reliable blood tests for plaque and tangle pathologies remain to be developed. Plaques and tangles often co-exist with other brain pathologies, including aggregates of transactive response DNA-binding protein 43 and Lewy bodies, but the extent to which these contribute to the severity of Alzheimer's disease is currently unknown...

OBJECTIVE: To describe the history of women in the American Otological Society (AOS). METHODS: Biographies of the early women of the AOS were compiled through review of the AOS transactions, their published scholarship, newspaper articles, and memorials. Interviews were conducted with the only two women to have led the society and also with former colleagues and family members of pioneering AOS women members who are no longer with us. The evolving gender composition of the society over time was researched from AOS membership lists and compared with data on surgical workforce composition from multiple sources such as the Association of American Medical Colleges, Accreditation Council for Graduate Medical Education, American Medical Association, and the American Academy of Otolaryngology-Head and Neck Surgery...

Extensive loss of noradrenaline-containing neurons and fibers is a nearly invariant feature of Alzheimer's Disease (AD). However, the exact noradrenergic contribution to cognitive and histopathological changes in AD is still unclear. Here, this issue was addressed following selective lesioning and intrahippocampal implantation of embryonic noradrenergic progenitors in developing rats. Starting from about 3 months and up to 12 months post-surgery, animals underwent behavioral tests to evaluate sensory-motor, as well as spatial learning and memory, followed by post-mortem morphometric analyses...

REVIEW
John M Levine
This paper reviews recent work on socially-shared cognition in small groups. Major attention is devoted to the impact of information and preference sharing on the achievement of group consensus and the consequences of consensus (and dissensus) for the group and its members. The literature is organized in terms of the task context in which sharing occurs (i.e., group problem-solving/decision-making tasks vs. group-productivity tasks). Topics covered include information sharing in hidden-profile situations, regulation of socio-cognitive conflict, shared mental models, transactive memory systems, and group discussions involving collective action...

BACKGROUND AIMS: Multiple steps are required to produce chimeric antigen receptor (CAR)-T cells, involving subset enrichment or depletion, activation, gene transduction and expansion. Open processing steps that increase risk of contamination and production failure are required. This complex process requires skilled personnel and costly clean-room facilities and infrastructure. Simplified, reproducible CAR-T-cell manufacturing with reduced labor intensity within a closed-system is highly desirable for increased availability for patients...

BACKGROUND: The developmental propensity model of antisocial behavior posits that several dispositional characteristics of children transact with the environment to influence the likelihood of learning antisocial behavior across development. Specifically, greater dispositional negative emotionality, greater daring, and lower prosociality-operationally, the inverse of callousness- and lower cognitive abilities are each predicted to increase risk for developing antisocial behavior. METHODS: Prospective tests of key predictions derived from the model were conducted in a high-risk sample of 499 twins who were assessed on dispositions at 10-17 years of age and assessed for antisocial personality disorder (APD) symptoms at 22-31 years of age...

State-machine replication is a common way of constructing general purpose fault tolerance systems. To ensure replica consistency, requests must be executed sequentially according to some total order at all non-faulty replicas. Unfortunately, this could severely limit the system throughput. This issue has been partially addressed by identifying non-conflicting requests based on application semantics and executing these requests concurrently. However, identifying and tracking non-conflicting requests require intimate knowledge of application design and implementation, and a custom fault tolerance solution developed for one application cannot be easily adopted by other applications...

REVIEW
Mauro DiNuzzo, Maiken Nedergaard
Brain activity during wakefulness is associated with high metabolic rates that are believed to support information processing and memory encoding. In spite of loss of consciousness, sleep still carries a substantial energy cost. Experimental evidence supports a cerebral metabolic shift taking place during sleep that suppresses aerobic glycolysis, a hallmark of environment-oriented waking behavior and synaptic plasticity. Recent studies reveal that glial astrocytes respond to the reduction of wake-promoting neuromodulators by regulating volume, composition and glymphatic drainage of interstitial fluid...

The term "legal capacity" refers to the ability of a person to make a valid declaration of his will or to accept such a declaration. This ability constitutes the main condition for the validity of the legal transaction. The legal transaction includes issues that are adjusted by the Civil Code with which the relations of the citizens in a society are regulated. General practitioners and legal advisors, in any case of a person with cognitive impairment of various severity, should take into account that the assessment tests of the cognitive functions are not by themselves diagnostic of the dementia and they cannot be used as the only way of evaluation of the capacity of patients with cognitive impairment or possible dementia to respond to the needs of everyday life and in more complex decisions, such as the legal capacity...

Long-term recognition memory for some pictures is consistently better than for others (Isola, Xiao, Parikh, Torralba, & Oliva, IEEE Transaction on Pattern Analysis and Machine Intelligence (PAMI), 36(7), 1469-1482, 2014). Here, we investigated whether pictures found to be memorable in a long-term memory test are also perceived more easily when presented in ultra-rapid RSVP. Participants viewed 6 pictures they had never seen before that were presented for 13 to 360 ms per picture in a rapid serial visual presentation (RSVP) sequence...

Recently developed information communication technologies, particularly the Internet, have affected how we, both as individuals and as a society, create, store, and recall information. The Internet also provides us with a great opportunity to study memory using transactional large-scale data in a quantitative framework similar to the practice in natural sciences. We make use of online data by analyzing viewership statistics of Wikipedia articles on aircraft crashes. We study the relation between recent events and past events and particularly focus on understanding memory-triggering patterns...

Understanding the dynamic nature of sex work is important for explaining the course of HIV epidemics. While health and development interventions targeting sex workers may alter the dynamics of the sex trade in particular localities, little has been done to explore how large-scale social and structural changes, such as economic recessions-outside of the bounds of organizational intervention-may reconfigure social norms and attitudes with regards to sex work. Zimbabwe's economic collapse in 2009, following a period (2000-2009) of economic decline, within a declining HIV epidemic, provides a unique opportunity to study community perceptions of the impact of socio-economic upheaval on the sex trade...

Hyperphosphorylated transactive response DNA-binding protein 43 (TDP-43, encoded by TARDBP ) proteinopathy has recently been described in ageing and in association with cognitive impairment, especially in the context of Alzheimer's disease pathology. To explore the role of mixed Alzheimer's disease and TDP-43 pathologies in clinical Alzheimer's-type dementia, we performed a comprehensive investigation of TDP-43, mixed pathologies, and clinical Alzheimer's-type dementia in a large cohort of community-dwelling older subjects...
