Adverse experiences in early childhood and their longitudinal impact on later behavioral problems of children living in poverty

BackgroundAdverse childhood experiences (ACEs) are an identified risk factor for the social and emotional development of children. What is less known is the long-term effects of ACEs when poverty and ACEs coincide.ObjectiveUsing longitudinal cohort-panel data, we examined whether exposure to ACEs by the age of three among poor children would longitudinally result in behavioral problems at ages three, five, nine, and 15, after controlling for mothers’ socioeconomic status and their children’s characteristics.Participants and settingWe used a subsample of 2750 children and their parents living in urban poverty from the Fragile Families and Child Wellbeing study.MethodsLogistic regression modeling was used to obtain adjusted odds ratios of ACE categories predicting behavioral problems after accounting for family socioeconomic position.ResultsOur findings indicate that experiencing ACEs in early childhood was significantly associated with later behavioral outcomes from childhood to adolescence. Exposure to multiple ACEs before the age of three was significantly associated with the top-risk behavior group at age five; the odd ratios were 2.0 (CI = 1.3–3.1) and 2.9 (CI = 1.8–4.6) for two ACEs and three or more ACEs, respectively. At both ages nine and 15, children experiencing two or more ACEs had 1.9 to 3.2 times higher odds to demonstrate more the top 10th percentile of behavioral problems. Among covariates, mothers’ race and education, and children’s gender and temperament were identified as significant factors to determine behavior problems.ConclusionsThe findings support policies and programs for families with children who have experienced economic disadvantages and early childhood adversity.

Organizational resilience and digital resources: Evidence from responding to exogenous shock by going virtual

Recent events have renewed attention to how organizations rely on digital resources in response to exogenous shock. Though the literature on organizational resilience indicates that this is best understood as a process through which organizational actors respond to a specific shock, most IS research attends to resilience as an outcome. Against that backdrop, we present a case study of how a university shifted to virtual teaching in response to a government-imposed lockdown during the COVID-19 pandemic. Adopting a digital resourcing perspective allowed us to reveal the organizational resilience process and the way digital resources shaped it. We found that the resilience process unfolded in stages as educators, assisted by students, managers, and IT personnel pivoted, adapted, and normalized into teaching virtually. Across these stages, digital resources took on specific roles as the resilience process progressed from the organization’s pre-shock accumulation of digital resources into its continued digitalization efforts. Based on these findings, we contribute to existing literature by advancing and empirically substantiating a process view of the role of digital resources in organizational resilience.     

Gender diversity in senior management,strategic change,and firm performance: Examining the mediating nature of strategic change in high tech firms

Only recently have enough women joined senior leadership positions in high tech firms for research on senior management gender diversity in high tech industries to be possible. We propose that senior management gender diversity fosters strategic change in high tech firms, especially under conditions where alliance formation intensity and top management team (TMT) educational background diversity are high, because the breadth of opportunity and knowledge associated with these conditions facilitates implementation of new ideas. Results show that both inter-organizational strategic alliance formation intensity and TMT educational background diversity positively moderate the relationship between senior management gender diversity and strategic change. We also find support for a moderated mediation model whereby a gender-diverse senior management positively impacts strategic change, which ultimately improves firm performance when the firm exhibits high alliance formation intensity and has a TMT that is diverse across educational background.     

Demystifying blockchain: A critical analysis of challenges,applications and opportunities

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.     

Positive Perspectives on the Profession: Reframing through Appreciative Inquiry

Change theories and Organization Development strategies have long followed the problem-solving approach of looking at organizations, identifying the weaknesses and introducing interventions to “stop doing the wrong things.” In its simplest form, this approach has been successful in a variety of situations and has a popular following. Consultants or internal reviewers look for the problems, identify the cause of the problem, and introduce the intervention (new rule) to eliminate the opportunity for the repetition of the “problem.” Problem-solving is a popular perspective through which change is initiated in politics, academia, and in social media. Eliminate the “bad” and pay attention to what we have been doing wrong to improve. This article first reviews the problems posed in past Hanna lectures to some major themes: (a) the need to address societal concerns, (b) the need to reduce sub-disciplinary fragmentation, (c) the problems inherent on university campuses as a result of politics and the economy, (d) the need to re-examine the over-reliance on the scientific research paradigm at the cost of phenomenological understandings, and (e) the framing of problems to be solved by professionals in our field. The introduction of Appreciative Inquiry and is then provided as an alternative approach to examine current contextual setting with the primary emphasis away from “What problems are you having?” and toward “What is working around here?”. This alternative suggests that in all organizations there is some positive force that is moving the organization forward, and the identification of that force (what works) can lay the ground work for doing more of “what works.” Finally, three examples of Appreciative Inquiry opportunities in action from our discipline are offered for consideration.     

Cumulative childhood trauma and psychological maladjustment of sexually abused children in Korea: Mediating effects of emotion regulation

The purpose of the present study was to identify the mediating effects of emotion regulation on the association between cumulative childhood trauma and behavior problems in sexually abused children in Korea, using structural equation modeling (SEM). Data were collected on 171 children (ages 6–13 years) referred to a public counseling center for sexual abuse in Seoul, Korea. Cumulative childhood traumas were defined on the basis of number of traumas (physical abuse, witnessing domestic violence, neglect, traumatic separation from parent, and sexual abuse) and the severity and duration of traumas. Children were evaluated by their parents on emotion regulation using the Emotion Regulation Checklist and internalizing and externalizing behavior problems using the Korean-Child Behavior Checklist. SEM analyses confirmed the complete mediation model, in which emotion dysregulation fully mediates the relationship between cumulative childhood traumas and internalizing/externalizing behavior problems. These findings indicate that emotion regulation is an important mechanism that can explain the negative effects of cumulative childhood traumas and that there is a need to focus on emotion regulation in sexually abused children exposed to cumulative trauma.     

Teaching Lean Six Sigma within A Supply Chain Context: The Airplane Supply Chain Simulation

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.

Communicating citizenship in China’s digital society

ABSTRACT

This research explores the (inter-) cultural dimension of communicating citizenship in China’s new media environment. It adopts speech codes theory as a theoretical and methodological framework to examine the historically situated and socially constructed meanings of citizenship and the normative communicative conduct for practicing “good citizenship” in China. Through a systematic analysis of Chinese online discourse surrounding two social events, this study captures one speech code pertaining to communicating citizenship that is premised on a paradox – citizenship is interpreted by the Chinese as a legal entitlement that they deserve, but it is simultaneously treated as an aspirational and unattainable ideal. Additionally, speaking sensibly and morally with a communal orientation is heavily emphasized in this speech code as it is considered a valuable communicative practice for performing “good citizenship.” Finally, participating in online collective actions such as “topping posts” is rendered an acceptable and effective way to communicate and enact citizen rights in China.
