[Organizational Climate and Culture: History, Current Status, Integration, and Change](https://www.annualreviews.org/content/journals/10.1146/annurev-orgpsych-020924-070545?TRACK=RSS) --- ### **Brainstem Circuits for Rhythm Generation and Coordination of Orofacial Movements | Fan Wang and Jun Takatoh** * **Main Arguments:** * The head serves as a **multifunctional nexus** where animals perform essential survival tasks such as breathing, feeding, gathering sensory input, and producing communication signals [1]. * Because anatomical resources are constrained, the same oropharyngeal structures must participate in **multiple behaviors**, necessitating precise coordination to avoid life-threatening errors like choking or aspiration [1]. * **Brainstem circuits** are the primary controllers that choreograph these complex actions, operating largely outside of conscious awareness to manage multiple muscle groups simultaneously [1]. * **Key Takeaways:** * The brainstem achieves remarkable precision and adaptability by **interacting between different rhythm-generating circuits** to weave distinct actions—such as whisking and sniffing—into integrated behaviors [1]. * Recent technological advances, including **circuit dissection, targeted manipulations, and large-scale electrophysiological recordings**, are allowing researchers to identify the specific neurons and functional connections supporting these actions [1]. * These circuits are capable of **flexible control**, ensuring that vital functions like breathing and eating can proceed without conflict [1]. * **Important Details:** * The research focuses on how the brain achieves effective control over **orofacial actions**, which represent one of biology's most demanding motor challenges [1]. * The circuitry must support actions that are both **precise and coordinated**, yet adaptable to changing environmental needs [1]. --- ### **Organizational Climate and Culture: History, Current Status, Integration, and Change | Benjamin Schneider, Mark G. Ehrhart, and William H. Macey** * **Main Arguments:** * **Organizational climate and culture** are distinct but related constructs that have historically been studied using different methodologies: climate via **quantitative/survey approaches** and culture via **qualitative methods** [2]. * While climate research has evolved to focus on specific strategic outcomes like **service and safety**, culture research typically explores the **deeper meanings, norms, and values** that employees attach to their organizations [2]. * The authors argue for the **integration of research** on these two constructs to provide a more holistic understanding of how employees interpret organizational actions and decisions [2]. * **Key Takeaways:** * Early climate research faced significant challenges regarding **validity and levels of analysis**, but since the 1980s, it has successfully focused on specific organizational outcomes [2]. * Culture research provides insight into **organizational interpretive frameworks** but has historically lacked attention to specific performance outcomes [2]. * An integrative approach is a useful basis for **understanding and facilitating organizational change** and long-term effectiveness [2]. * **Important Details:** * Climate is characterized by its focus on **employee perceptions** of what is important for effectiveness, while culture focuses on the **underlying values** that drive those perceptions [2]. * The integration of these constructs helps explain how people in organizations interpret **decisions and actions** [2]. --- ### **Prioritizing Marginality and Resistance in Racial Identity Research | Leoandra Onnie Rogers and Vanessa Cordova-Lopez** * **Main Arguments:** * Racial identity is more than an individual-level psychological resource; for youth at the margins of society, it is a **collective process of resistance for liberation** [3]. * Current racial identity research is often limited by a focus on the individual and discrete racial categories, failing to account for the **radical potential** that exists at the edges of the field [3]. * The researchers utilize the **m(ai)cro framework**, which identifies the **macrosystem** (broad social and cultural ideologies) as the epicenter of human development [3]. * **Key Takeaways:** * The authors propose **four "m(ai)cro shifts"** to advance the field: 1. Moving from the individual to include the **sociopolitical context** [3]. 2. Moving from discrete categories to include **intersectionality and multiraciality** [3]. 3. Expanding from a focus on racial oppression to include **whiteness and privilege** [3]. 4. Shifting from quantitative measures of "how much" identity to prioritizing **meaning-making and lived experience** [3]. * Racial identity should be understood as a resource that flourishes within **marginalized families and communities**, fueling collective resistance [3]. * **Important Details:** * Racial identity is a **key developmental resource**, particularly for Black youth and youth from other racially minoritized communities in the United States [3]. * The goal of these proposed shifts is to scaffold scholarship that is directed toward **collective liberation** [3]. --- ### **Sex Differences in Affective Disorders: A Developmental Neuroscience Framework on the Role of Puberty | Cecile D. Ladouceur** * **Main Arguments:** * The risk of **affective disorders** increases significantly during adolescence, with girls facing **roughly twice the risk** observed in boys [4]. * The review proposes a **heuristic model** suggesting that **pubertal hormones** modulate the maturation of specific brain circuitry in sex-specific ways that increase vulnerability to depression and anxiety [4]. * The maturation of **mesocorticolimbic circuitry**—including the amygdala, nucleus accumbens, and ventromedial prefrontal cortex—is a critical target for these hormonal effects [4]. * **Key Takeaways:** * In girls, gonadal hormones may heighten **neural sensitivity to threat** and **dampen reward responsiveness** [4]. * These hormonal changes can **bias socio-affective learning toward avoidance** during adolescence, a period characterized by heightened neuroplasticity [4]. * Integrating evidence from **human neuroimaging and animal studies** is essential for identifying convergent hormonal pathways that confer risk [4]. * **Important Details:** * The framework emphasizes the importance of identifying **sex-specific risk markers** to inform **mechanism-based early interventions** [4]. * Affective disorders like anxiety and depression are specifically linked to the maturation of circuits that process **threat and reward** [4].
