‘Resting-State MRI Functional Connectivity as a Neural Correlate of Multidomain Lifestyle Adherence’
“Prior research has demonstrated the importance of a healthy lifestyle to protect brain health and diminish dementia risk in later life. While a multidomain lifestyle provides an ecological perspective to voluntary engagement, its association with brain health is still under-investigated. … Self-reported exercise engagement, cognitive activity engagement, healthy diet adherence, and social activity engagement were included to examine potential phenotypes of an individual’s lifestyle adherence. … The features that show consistently high importance to the classification model were functional connectivity mainly between nodes located in different prior-defined functional networks.” Find the paper and the full list of authors in Scientific…

Odom explains why companies need ‘a clear purpose’ to be effective
“We’re in the middle of a pivotal moment where purpose, value and meaning are essential for business,” Curtis Odom, associate teaching professor of management and organizational development, writes. It’s vital that businesses identify “a clear purpose [that] can help a company differentiate itself from competitors, inspire and motivate employees, and build or maintain a strong brand identity.” Odom continues by describing how leaders can re-evaluate, and re-instill, purpose in their company and among their employees.

‘How Informal Entrepreneurship Impacts Innovation in Emerging Economies’
“New ventures in emerging markets, initially created informally, suffer from costs that persist and constrain a firm’s ability to innovate even after they formalize their status. … Informally created new ventures are more likely to develop imitative rather than innovative new products. However, being acquired by other firms and improvements in the national innovation system can weaken the persistence of these informality costs. … The concept of internal imprinting … captures how the internal characteristics of a company result in the establishment of practices that persist over time.” Find the paper and the list of authors at the Insights @…

‘Attention to Emotional Stimuli Across Adulthood and Older Age: A Novel Application of Eye-Tracking Within the Home’
“Previous research has used stationary eye-tracking in the lab to examine age differences in attentional deployment, showing that older adults display gaze patterns toward positive stimuli. … However, the lab environment may lead to different emotion regulation behavior among older adults compared to what they do in their everyday life. We, therefore, present the first use of stationary eye-tracking within participants’ homes to examine gaze patterns toward video clips of varying valence and to study age differences in emotional attention … in a more naturalistic environment.” Read the paper and see the full list of authors at APA PsycNet.

‘How Digitally Enhanced Autonomous Teams Make Chinese Companies More Agile’
“Chinese companies are reinventing management through an approach called “digitally enhanced directed autonomy” (DEDA). DEDA uses digital platforms to give frontline employees direct access to corporate resources and capabilities, allowing them to organize themselves around business opportunities without managerial intervention. Autonomy is directed where it is needed and tracked. By giving teams the freedom to design, produce, and sell their products, companies can foster innovation, increase employee engagement, and improve customer satisfaction.” Read the paper and see the full list of authors at the Insights @ Center for Emerging Markets.

‘Optimal Cancer Evasion in a Dynamic Immune Microenvironment Generates Diverse Post-Escape Tumor Antigenicity Profiles’
“The failure of cancer treatments, including immunotherapy, continues to be a major obstacle in preventing durable remission. This failure often results from tumor evolution, both genotypic and phenotypic, away from sensitive cell states. Here, we propose a mathematical framework for studying the dynamics of adaptive immune evasion that tracks the number of tumor-associated antigens available for immune targeting.” Read the paper and see the full list of authors at ELife Sciences.

‘Conceptualizing Human–Nature Relationships: Implications of Human Exceptionalist Thinking’
“Human exceptionalism (HE) … involv[es] the belief that humans and human societies exist independently of the ecosystems in which they are embedded, promoting a sharp ontological boundary between humans and the rest of the natural world. In this paper, we introduce HE in more depth, exploring the impact of HE on perceptions of the human–nature relationship, the role of culture in HE, and speculating on the origins of HE. We consider potential implications for environmental decision-making, conservation and environmental science, and promoting proenvironmental behavior. ” Read the paper and see the full list of authors at Topics in Cognitive Science.

‘Cell Invasion During Competitive Growth of Polycrystalline Solidification Patterns’
“Spatially extended cellular and dendritic array structures forming during solidification processes … are generally polycrystalline. Both the array structure within each grain and the larger scale grain structure determine the performance of many structural alloys. How those two structures coevolve during solidification remains poorly understood. By in situ observations of microgravity alloy solidification experiments onboard the International Space Station, we have discovered that individual cells from one grain can unexpectedly invade a nearby grain of different misorientation, either as a solitary cell or as rows of cells.” Read the paper and see the full list of authors in Nature Communications.

‘Body Mechanics, Optimality and Sensory Feedback in the Human Control of Complex Objects’
“Humans are adept at a wide variety of motor skills, including the handling of complex objects and using tools. Advances to understand the control of voluntary goal-directed movements have focused on simple behaviors such as reaching, uncoupled to any additional object dynamics. … This study examined a task with internal dynamics, inspired by the daily skill of transporting a cup of coffee, with additional expected or unexpected perturbations to probe the structure of the controller.” Read the paper and see the full list of authors in Neural Computation.

‘Changes in Water Flow Alter Community Dynamics in Oyster Reefs’
Professor of marine and environmental sciences Jonathan Grabowski, with professor Sean Powers from the University of South Alabama, has published a new paper in Ecosphere. “Water flow can influence individual fitness and local population dynamics, but less is known about the collective response of natural communities to alteration in water flow. … To examine how changes in water flow affected initial larval settlement patterns of epifaunal and infaunal animals, colonization of larger individuals, and prey survival, we manipulated water flow (−50% or +47%) in situ using large wooden channels over small experimental oyster reefs.”

‘Why Do We Need to Learn about Citational Practices?’
“How do you decide which papers to cite, how many, and from which particular sources? We reflect and discuss the implications of these critical questions based on our experiences in the panel and workshops on the topic of citational justice that took place at CSCW, CLIHC, and India HCI in 2021.” Read the paper and see the full list of authors in XRDS: Crossroads.

‘Protected or Porous: A Comparative Analysis of Threat Detection Capability of IoT Safeguards’
“Consumer Internet of Things (IoT) devices are increasingly common, from smart speakers to security cameras, in homes. Along with their benefits come potential privacy and security threats. To limit these threats a number of commercial services have become available (IoT safeguards). The safeguards claim to provide protection against IoT privacy risks and security threats. However, the effectiveness and the associated privacy risks of these safeguards remains a key open question. In this paper, we investigate the threat detection capabilities of IoT safeguards for the first time.” Read the paper and see the full list of authors in ArXiv.

‘Going Beyond Binary: Rapid Identification of Protein–Protein Interaction Modulators’
“Kinetic target-guided synthesis (KTGS) is a powerful screening approach that enables identification of small molecule modulators for biomolecules. While many KTGS variants have emerged, a majority of the examples suffer from limited throughput and a poor signal/noise ratio, hampering reliable hit detection. Herein, we present our optimized multifragment KTGS screening strategy that tackles these limitations.” Read “Going Beyond Binary: Rapid Identification of Protein–Protein Interaction Modulators Using a Multifragment Kinetic Target-Guided Synthesis Approach” and see the full list of authors in the Journal of Medicinal Chemistry.

Breakthrough in early osteoarthritis diagnoses, potentially improving patient outcomes
“Early [osteoarthritis] diagnosis is critical. … Computed tomography (CT) has been considered for cartilage imaging … by introducing radio-opaque contrast agents like ioxaglate (IOX) into the joint. IOX, however, is anionic and thus repelled by negatively charged cartilage glycosaminoglycans. … Here we engineer optimally charged cationic contrast agents … such that they can penetrate through the full thickness of cartilage.” Read “Cationic Carrier Mediated Delivery of Anionic Contrast Agents in Low Doses Enable Enhanced Computed Tomography Imaging of Cartilage for Early Osteoarthritis Diagnosis” and see the full list of authors in ACS Publications.
