Do nonphysical punishments reduce antisocial behavior more than spanking? a comparison using the strongest previous causal evidence against spanking

<p>Abstract</p> <p>Background</p> <p>The strongest causal evidence that customary spanking increases antisocial behavior is based on prospective studies that control statistically for initial antisocial differences. None of those studies have investigated alternative disciplinary tactics that parents could use instead of spanking, however. Further, the small effects in those studies could be artifactual due to residual confounding, reflecting child effects on the frequency of all disciplinary tactics. This study re-analyzes the strongest causal evidence against customary spanking and uses these same methods to determine whether alternative disciplinary tactics are more effective in reducing antisocial behavior.</p> <p>Methods</p> <p>This study re-analyzed a study by Straus et al.<abbrgrp><abbr bid="B1">1</abbr></abbrgrp> on spanking and antisocial behavior using a sample of 785 children who were 6 to 9 years old in the 1988 cohort of the American National Longitudinal Survey of Youth. The comprehensiveness and reliability of the covariate measure of initial antisocial behavior were varied to test for residual confounding. All analyses were repeated for grounding, privilege removal, and sending children to their room, and for psychotherapy. To account for covarying use of disciplinary tactics, the analyses were redone first for the 73% who had reported using at least one discipline tactic and second by controlling for usage of other disciplinary tactics and psychotherapy.</p> <p>Results</p> <p>The apparently adverse effect of spanking on antisocial behavior was replicated using the original trichotomous covariate for initial antisocial behavior. A similar pattern of adverse effects was shown for grounding and psychotherapy and partially for the other two disciplinary tactics. All of these effects became non-significant after controlling for latent comprehensive measures of externalizing behavior problems.</p> <p>Conclusions</p> <p>These results are consistent with residual confounding, a statistical artifact that makes all corrective actions by parents and psychologists appear to increase children's antisocial behavior due to child effects on parents. Improved research methods are needed to discriminate between effective vs. counterproductive implementations of disciplinary tactics. How and when disciplinary tactics are used may be more important than which type of tactic is used.</p

Patterns of Psychotropic Medication at Admission for Youth in Residential Care

High levels of psychotropic medication use and polypharmacy are common for emotionally and behaviorally troubled youth entering residential care. Polypharmacy has often been characterized as an especially serious problem in this vulnerable population. Latent Class Analysis was used to identify medication subgroups for 636 youth in an intensive residential program. Additionally, auxiliary analyses (e.g., diagnoses, demographics, expressed problem behaviors) were used to identify the personal and behavioral attributes associated with individuals in each of the latent classes. Three distinct medication patterns emerged: low/no psychotropic medication, the combination of antidepressant and antipsychotic medications, and multiple psychotropic medications. The latent classes were significantly different from one another on 12 of the 14 variables, helping explicate how patient and clinical characteristics underlie patterns of psychotropic medication use. Findings of this study, combined with additional research, hold promise for leading to improved, youth-centered prescribing practices. Our findings also highlight the need for careful monitoring of the types and range of medications that some youth are prescribed, and research on how youth with certain background characteristics are more likely to get prescribed multiple psychotropic medications. For youth experiencing higher levels of psychotropic polypharmacy, medication regimens need thoughtful reassessment using the principle of sufficiency as the foundation for medication management

Do Open Access Electronic Theses and Dissertations Diminish Publishing Opportunities in the Sciences?

In academia, there is a growing acceptance of sharing the final electronic version of graduate work, such as a thesis or dissertation, in an online university repository. Though previous studies have shown that journal editors are willing to consider manuscripts derived from electronic theses and dissertations (ETDs), faculty advisors and graduate students continue to raise concerns that online discoverability of ETDs negatively impact future opportunities to publish those findings. The current study investigated science journal policies on open access ETDs and found that more than half of the science journals responding (51.4%) reported that manuscripts derived from openly accessible ETDs are welcome for submission and an additional 29.1 percent would accept revised ETDs under certain conditions

The Photophysics of the Carrier of Extended Red Emission

Interstellar dust contains a component which reveals its presence by emitting a broad, unstructured band of light in the 540 to 950 nm wavelength range, referred to as Extended Red Emission (ERE). The presence of interstellar dust and ultraviolet photons are two necessary conditions for ERE to occur. This is the basis for suggestions which attribute ERE to an interstellar dust component capable of photoluminescence. In this study, we have collected all published ERE observations with absolute-calibrated spectra for interstellar environments, where the density of ultraviolet photons can be estimated reliably. In each case, we determined the band-integrated ERE intensity, the wavelength of peak emission in the ERE band, and the efficiency with which absorbed ultraviolet photons are contributing to the ERE. The data show that radiation is not only driving the ERE, as expected for a photoluminescence process, but is modifying the ERE carrier as manifested by a systematic increase in the ERE band's peak wavelength and a general decrease in the photon conversion efficiency with increasing densities of the prevailing exciting radiation. The overall spectral characteristics of the ERE and the observed high quantum efficiency of the ERE process are currently best matched by the recently proposed silicon nanoparticle (SNP) model. Using the experimentally established fact that ionization of semiconductor nanoparticles quenches their photoluminescence, we proceeded to test the SNP model by developing a quantitative model for the excitation and ionization equilibrium of SNPs under interstellar conditions for a wide range of radiation field densities.Comment: 42 p., incl. 8 fig.

On the Biological Importance of the 3-hydroxyanthranilic Acid: Anthranilic Acid Ratio

Of the major components of the kynurenine pathway for the oxidative metabolism of tryptophan, most attention has focussed on the N-methyl-D-aspartate (NMDA) receptor agonist quinolinic acid, and the glutamate receptor blocker kynurenic acid. However, there is increasing evidence that the redox-active compound 3-hydroxyanthranilic acid may also have potent actions on cell function in the nervous and immune systems, and recent clinical data show marked changes in the levels of this compound, associated with changes in anthranilic acid levels, in patients with a range of neurological and other disorders including osteoporosis, chronic brain injury, Huntington’s disease, coronary heart disease, thoracic disease, stroke and depression. In most cases, there is a decrease in 3-hydroxyanthranilic acid levels and an increase in anthranilic acid levels. In this paper, we summarise the range of data obtained to date, and hypothesise that the levels of 3-hydroxyanthranilic acid or the ratio of 3-hydroxyanthranilic acid to anthranilic acid levels, may contribute to disorders with an inflammatory component, and may represent a novel marker for the assessment of inflammation and its progression. Data are presented which suggest that the ratio between these two compounds is not a simple determinant of neuronal viability. Finally, a hypothesis is presented to account for the development of the observed changes in 3-hydroxyanthranilic acid and anthranilate levels in inflammation and it is suggested that the change of the 3HAA:AA ratio, particularly in the brain, could possibly be a protective response to limit primary and secondary damage

Parental Attitudes toward Genetic Testing for Pediatric Deafness

Recent molecular genetic advances have resulted in genetic testing becoming an option for deaf individuals and their families. However, there is little information about the interest in such testing. To investigate this issue, parents with normal hearing who have one or more deaf children were surveyed about their attitudes toward diagnostic, carrier, and prenatal genetic testing for deafness. This population was chosen because it represents the majority of individuals who are encountered in clinical practice, given that 90%–95% of deaf individuals are born to persons with normal hearing. Of 328 surveys distributed, 96 were completed and returned. Of the respondents, 96% recorded a positive attitude toward genetic testing for deafness, including prenatal testing, although none would use this information to terminate an affected pregnancy. All respondents had a poor understanding of genetics, with 98% both incorrectly estimating the recurrence risk of deafness and misunderstanding the concept of inheritance. Notably, these findings were similar in the group who had had genetic testing for their children and in the group who had not, suggesting either that the parents who received genetic testing did not receive genetic counseling or that the counseling was not effective. On the basis of these results, it was concluded that this population is interested in the use of genetic testing and that testing should not be done without first providing formal genetic counseling. Appropriate counseling can help parents to understand the risks, benefits, and limitations of genetic testing

hERG Gating Microdomains Defined by S6 Mutagenesis and Molecular Modeling

Human ether-à-go-go–related gene (hERG) channels mediate cardiac repolarization and bind drugs that can cause acquired long QT syndrome and life-threatening arrhythmias. Drugs bind in the vestibule formed by the S6 transmembrane domain, which also contains the activation gate that traps drugs in the vestibule and contributes to their efficacy of block. Although drug-binding residues have been identified, we know little about the roles of specific S6 residues in gating. We introduced cysteine mutations into the hERG channel S6 domain and measured mutational effects on the steady-state distribution and kinetics of transitions between the closed and open states. Energy-minimized molecular models based on the crystal structures of rKv1.2 (open state) and MlotiK1 and KcsA (closed state) provided structural contexts for evaluating mutant residues. The majority of mutations slowed deactivation, shifted conductance voltage curves to more negative potentials, or conferred a constitutive conductance over voltages that normally cause the channel to close. At the most intracellular extreme of the S6 region, Q664, Y667, and S668 were especially sensitive and together formed a ringed domain that occludes the pore in the closed state model. In contrast, mutation of S660, more than a full helical turn away and corresponding by alignment to a critical Shaker gate residue (V478), had little effect on gating. Multiple substitutions of chemically distinct amino acids at the adjacent V659 suggested that, upon closing, the native V659 side chain moves into a hydrophobic pocket but likely does not form the occluding gate itself. Overall, the study indicated that S6 mutagenesis disrupts the energetics primarily of channel closing and identified several residues critical for this process in the native channel
