How to make the fourth revolution: Human factors in the adoption of electronic instructional aids

The prospects and problems of getting higher education in the United States (high school and above) to more fully utilize electronic technologies are examined. Sociological, psychological, and political factors are analyzed to determine the feasibility of adopting electronic instructional techniques. Differences in organizations, attitudes, and customs of different kinds of students, teachers, administrators, and publics are crucial factors in innovation

Audit Report Timeliness in Local Governments: An Observation of North Carolina Governmental Units’ Response to State-Imposed Deadlines and Consequences

To provide citizens with transparent financial information regarding the health of their respective districts, local government unit leaders must furnish governmental audit reports in a timely manner. Further, for management to effectively implement auditor suggestions for improvements, leaders must have accessibility to timely audited information. Many governmental units in the state of North Carolina have demonstrated significant lags in reporting timeliness and often miss state-mandated deadlines. Therefore, this research utilized ordinary least-squares regression to estimate the effects the variables representing report message and managerial competency, accountability, and audit environment groups had on the time required for each unit to file its annual audit report with the North Carolina Department of State Treasurer. Logistic regression was also used to estimate the effects these groups of variables had on units that filed audit reports after the North Carolina state-mandated submission deadline compared to those that filed on-time. Data was collected from audited financial statements, auditor reports, and financial information reports for units throughout N.C. for the fiscal year 2021. Two variables, findings and single audit, were found to have significant influence on units failing to meet state-mandated deadlines. The variable findings was also found to have statistical influence on audit report submission delays by local government units

Testing a Brief Treatment to Reduce the Frequency of Panic Attacks in a Clinical Outpatient Population

Panic attacks, the key symptom of panic disorder and an associated feature of various anxiety disorders, are extremely distressing events that can negatively impact an individual’s mental health, physical health, and quality of life. This study validated a brief treatment for panic attacks, designed to reduce the frequency of panic attacks after the first session, in an outpatient clinical population. One participant was recruited to participate in this single case experimental ABA design with follow-up, where a reversal was not expected, due to the maintenance of positive effects. The treatment included both cognitive and behavioral techniques. The results were analyzed using simulation modeling analysis, as well as visual analysis. This treatment produced clinically significant effects by reducing the frequency and severity of panic attacks, reducing symptoms of anxiety and panic, decreasing the frequency of cognitive distortions, and increasing the level of functioning. Additionally, these gains were maintained at a 3- month follow-up. It is hoped that this intervention can help clinicians treat panic disorder and improve their effectiveness and efficiency by reducing the time needed to significantly decrease panic attacks. It is also hoped that this intervention might be expanded for use with other panic-related anxiety disorders. Finally, it is possible that this study will encourage efforts toward briefer treatments for other disorders

Banking Geography and Cross-Fertilization in the Productivity Growth of US Commercial Banks

The US banking industry offers a unique, natural and fertile environment to study geography's effects on banks' behavior and performance. The literature on banks' operating performance, while extensive, says little about the influence of spatial interactions on banks' performance. We compute and examine, using a physical distance-based spatio-temporal empirical model, the state-wide total factor productivity growth (TFPG) indices of US commercial banks for each state for the 1971-1995 period. We observe that the productivity growth of commercial banks in state i depends strongly, positively, and contemporaneously on the productivity growth of commercial banks located in state i's contiguous states. Further, “regulatory space” appears to induce frictions and lessen the documented spatial interactions. These findings support our plea that research on commercial banking sector's behavior need to pay a particular attention to the effects of banking geography.Spatial, Commercial Banks, Total Factor Productivity Growth, Kalman Filter

Nucleation at the DNA supercoiling transition

Twisting DNA under a constant applied force reveals a thermally activated transition into a state with a supercoiled structure known as a plectoneme. Using transition state theory, we predict the rate of this plectoneme nucleation to be of order 10^4 Hz. We reconcile this with experiments that have measured hopping rates of order 10 Hz by noting that the viscosity of the bead used to manipulate the DNA limits the measured rate. We find that the intrinsic bending caused by disorder in the base-pair sequence is important for understanding the free energy barrier that governs the transition. Both analytic and numerical methods are used in the calculations. We provide extensive details on the numerical methods for simulating the elastic rod model with and without disorder.Comment: 18 pages, 15 figure

Clinical characteristics and treatment outcomes of women with heroin dependence in Johannesburg, South Africa

Background. There has been a steady increase in the number of women with heroin dependence in South Africa (SA). Data from developed countries suggest that women with substance use disorder have unique treatment needs. There are limited SA data on women with heroin dependence and their response to treatment.Objectives. To describe the clinical and psychosocial characteristics of women entering inpatient rehabilitation for heroin dependence, determine the outcomes of treatment 3 and 9 months after rehabilitation, and compare these findings with male heroin users.Methods. We conducted a longitudinal study of 44 women with heroin dependence who were admitted to a rehabilitation facility in the West Rand Municipality of Gauteng Province, SA. The participants were assessed during admission and 3 and 9 months after leaving inpatient rehabilitation. Structured interviews measured changes in drug use, psychopathology, social functioning, injecting and sexual behaviour, criminality and general health. Statistical analysis of these outcomes and comparison between women and men at 3 months and 9 months was performed by a generalised estimating equation. Fixed and time-varying covariates were included in the models.Results. At baseline, 40% of female participants were HIV-positive, 50% engaged in sex work, 27% were injecting heroin users, and 75% were diagnosed with a comorbid mental illness. Thirty-seven (84%) and 30 (68%) were re-interviewed at the 3- and 9-month follow-up points, respectively. Of these, 6 were abstinent from all substances at 3 months and 2 at 9 months. Compared with males, females had a higher prevalence of HIV infection (p=0.006) and mental illness (p=0.0002) at enrolment. At 9 months, women had similar levels of drug use and criminality to men but scored significantly worse in terms of general health, social function and risky sexual behaviour.Conclusions. Women with heroin dependence in Johannesburg have high rates of HIV infection and comorbid mental illness and low rates of abstinence after inpatient detoxification and psychosocial therapy. Women fared worse than men in many domains of treatment outcome. This study builds evidence for the need for gender-sensitive substance rehabilitation facilities in SA.
