Reply to Comment on "Comparison of the Lateral Retention Forces on Sessile, Pendant, and Inverted Sessile Drops".

We address the issues raised in the Tadmor article (Tadmor, T., et al. Comment on "Comparison of the Lateral Retention Forces on Sessile, Pendant, and Inverted Sessile Drops". Langmuir 2019, 10.1021/acs.langmuir.9b02660). In particular, we explain why we did not use Tadmor's theory to explain our results.

Use of inpatient mental health services by members of ethnic minority groups.

National data on psychiatric hospitalization point to marked ethnic-related differences. Blacks and Native Americans are considerably more likely than Whites to be hospitalized; Blacks are more likely than Whites to be admitted as schizophrenic and less likely to be diagnosed as having an affective disorder; Asian Americans/Pacific Islanders are less likely than Whites to be admitted, but remain for a lengthier stay, at least in state and county mental hospitals. These differences are clear-cut, but they ignore a major source of care: psychiatric hospitalization in placements other than psychiatric units and hospitals. Explanations for observed minority-White differences in hospitalization can be evaluated only partially or not at all: Such explanations include ethnic-related differences in socioeconomic standing and in the prevalence of major psychopathology; differential stigma, or capacity to tolerate or support a dysfunctional significant other; access and use of alternative services; and bias in the behavior of gatekeepers, especially practitioners assigning diagnostic labels and making involuntary commitment decisions. More research is needed to help explain these striking differences in utilization.

Validity of an MMPI classification of problem drinker-drivers.

An empirical typology of problem drinker-drivers based on the Minnesota Multiphasic Personality Inventory (MMPI) was evaluated. Relationships were demonstrated between this typology and several kinds of external criteria: alcoholism symptoms, reasons for drinking, treatment participation and outcome and medical complications. Indicators of typological validity were further evaluated in the context of alternative means of scoring and categorizing MMPI profiles. Relationships of criteria with the drinker-driver typology were generally stronger than with other uses of the MMPI. They were, however, weaker than those formed with an unweighted combination of three scales: Psychopathic Deviate, Depression and the K (test-taking attitude) validity scales. Results suggest that the typology divides the population of drinking drivers meaningfully and more powerfully than several, but not all, alternative uses of MMPI profiles.

Alcohol-related problems among black, Hispanic and white men: the contribution of neighborhood poverty.

OBJECTIVE: We examined the cross-sectional relationships between race/ethnicity, neighborhood poverty and alcohol-related problems among black, Hispanic and white male drinkers. Test hypotheses were that black and Hispanic men living in more impoverished neighborhoods would report increased numbers of alcohol-related problems than comparable white men. METHOD: Study hypotheses were tested in a sample of 744 black, Hispanic and white men participating in the 1992 National Alcohol Follow-up Survey. Study hypotheses were analyzed using generalized linear model regression analysis. RESULTS: Neighborhood poverty had a greater effect on alcohol-related problems in black than in white men, partially supporting our hypothesis. Black men living in more impoverished neighborhoods reported greater numbers of alcohol-related problems than comparable white men; there were no race differences among more affluent men. Neighborhood poverty had little effect on alcohol-related problems in Hispanic men. CONCLUSIONS: Findings suggest that, giving unfavorable economic conditions, black men will report greater numbers of alcohol-related problems than comparable white men.

Reasons for drinking among problem drinker-drivers: client and counselor reports during treatment.

In a program for problem drinker-drivers, relationships were examined among 14 psychological and physical reasons for drinking. The two sets of ratings were separately factor analyzed. The factors were corroborated by correlating them between factor sets and with external variables: MMPI subscales, Michigan Alcoholism Screening Test, record of DWI convictions, and dropping out of the program. Results indicated that reasons for drinking form patterns related to psychological adjustment.

An empirical typology of problem drinkers from the Michigan Alcoholism Screening Test.

In a program of treatment for persons convicted of driving while intoxicated, data from 504 male participants were collected and analyzed to identify groups homogeneous with respect to symptoms and consequences of problem drinking as indicated on the Michigan Alcoholism Screening Test (MAST). Cluster analysis of MAST responses yielded 7 such groups, differing in level and pattern of alcohol-related problems. This classification was shown: (a) to be homogeneous and reliable; (b) to discriminate effectively within several sets of external criteria--specifically, scales and profiles from the Minnesota Multiphasic Personality Inventory (MMPI) and clinical ratings of reasons for drinking and of participation and outcome from treatment; and (c) to predict alcoholism criteria more powerfully than dimensional use of the MAST. Categorical representation of alcoholism from its psychosocial symptoms was shown to be a valid and valuable structural approach.

A confirmatory factor analysis of the BASIS-32 in racial and ethnic samples.

The present study performed confirmatory factor analysis across major racial and ethnic groups of the BASIS-32, a measure of functional status of persons receiving mental health treatment and suitable for routine assessment mental health care. The purpose was to perform a preliminary investigation of cross-cultural equivalence in a county-level mental health program in a major metropolitan area. The results indicated a factor structure similar to that reported in the literature, and they suggested acceptable levels of agreement in structure between racial and ethnic minority groups and whites. The study revealed little reason to believe that the BASIS-32 varied in underlying structure across racial and ethnic boundaries, although further research is indicated.

Ethnic characteristics of mental disorders in five U.S. communities.

The study examined the ethnic ratio of 16 DSM-III mental disorders among White, Black, Hispanic, and Asian Americans. A total of 18,126 residents from 5 sites and 2,939 residents from the Epidemiological Catchment Area's Los Angeles site were studied separately. Logistic regression analysis was performed. Results showed that Blacks were significantly less likely than Whites to have major depressive episode, major depression, dysthymia, obsessive-compulsive disorder, drug and alcohol abuse or dependence, antisocial personality, and anorexia nervosa, but they were significantly more likely than Whites to have phobia and somatization. Lifetime prevalence rates of schizophrenia, obsessive-compulsive disorder, panic, and drug abuse or dependence were significantly lower among Hispanics than among Whites. Asians also had significantly lower rates than Whites of schizophreniform, manic episode, bipolar disorder, panic, somatization, drug and alcohol abuse or dependence, and antisocial personality. Compared with the overall findings, ethnic differences at the Los Angeles site were lessened between Blacks and Whites, enhanced between Hispanics and Whites, and basically unchanged between Asians and Whites.

Treatment participation and outcome in a program for problem drinker-drivers.

Relationships were examined between 13 predictor variables and two criteria of improvement in a program for problem drinker-drivers. Four measures of social background (income, educations, age, marital status), four measures of psychopathology based on the Minnesota Multiphasic Personality Inventory (MMPI), one measure of general alcoholism, and four indicators of treatment involvement served as predictor variables. Two factorially derived criteria served as outcome indicators, one reflecting general improvement, the other reflecting improved social adjustment, but a failure to reduce drinking. This second factor was interpreted as indicating resistance. Analysis included partial correlation and multiple regression, from which explained variance was completely partitioned into sources unique to each predictor, and sources shared by combinations of predictors. Results suggested that with other factors controlled, treatment involvement was linked both to improvement and to resistance. Similar conclusions were suggested for social background, but slightly different ones for psychopathology and alcoholism. Psychopathology was uniquely related to improvement; alcoholism, to resistance.

Collective versus mass behavior: a conceptual framework for temporary and permanent migration in Western Europe and the United States.

"Present theories treat migration as one basic movement. [In the present paper,] conceptualization of economic migration as collective rather than mass behavior has been proposed to overcome present theoretical inadequacies and facilitate empirical analyses. Permanent migration has been correctly regarded as statistically aggregated, institutionalized behavior. Temporary international labor migration is, however, a different phenomenon--one that is more accurately portrayed as a collective product. It is the culmination of nontraditional interactions between three major groups: the migrants, their employers and host nation-states. The development of collective behavior, including a noninstitutionalized role of the state, may be illustrated by Western European guestworkers and United States illegal aliens. Advantages of the conceptualization include easier cross-cultural comparisons, guidelines for predictability and recognition of the dual role of the state as both major actor in the migration process and social control agent."

Prevalence of environmental Aeromonas in South East Queensland, Australia: a study of their interactions with human monolayer Caco-2 cells.

AIMS: To investigate the prevalence of Aeromonas in a major waterway in South East Queensland, Australia, and their interactions with a gut epithelial model using Caco-2 cells. METHODS AND RESULTS: A total of 81 Aeromonas isolates, collected from a major waterway in South East Queensland, Australia, were typed using a metabolic fingerprinting method, and tested for their adhesion to HEp-2 and Caco-2 cells and for cytotoxin production on Vero cells and Caco-2 cells. Aeromonas hydrophila had the highest (43%) and Aeromonas veronii biovar sobria had the lowest (25%) prevalence. Four patterns of adhesion were observed on both HEp-2 and Caco-2 cell lines. Representative isolates having different phenopathotypes (nine strains) together with two clinical isolates were tested for their translocation ability and for the presence of virulence genes associated with pathogenic Escherichia coli. The rate and degree of translocation across Caco-2 monolayers varied among strains and was more pronounced with LogA pattern. Translocation was associated with the adherence of strains to Caco-2 cells microvilli, followed by internalization into Caco-2 cells. Two Aer. veronii biovar sobria strains were positive for the presence of heat-labile toxin genes, with one strain also positive for Shiga-like toxin gene. CONCLUSIONS: Pathogenic strains of Aeromonas carrying one or more virulence characteristics are highly prevalent in the waterways studied and are capable of translocating across a human enterocyte cell model. SIGNIFICANCE AND IMPACT OF THE STUDY: This study indicates that Aeromonas strains carrying one or more virulence properties are prevalent in local waterways and are capable of translocating in a human enterocyte cell culture model. However, their importance in human gastrointestinal disease has yet to be verified under competitive conditions of the gut.

An investigation into whether nursing student alter their attitudes and knowledge levels regarding HIV infection and AIDS following a 3-year programme leading to registration as a qualified nurse.

The purpose of this study was to examine whether a 3-year programme of nursing studies enabled nursing students to graduate from the course with greater knowledge and more positive attitudes towards HIV infection and AIDS than when they began the course. Students on a maths and information technology course were used as controls. The study involved the use of a questionnaire which gathered information about students' experience, knowledge, attitudes and moral judgement regarding HIV infection and AIDS. The experimental hypothesis stated that nursing students would show a greater increase in knowledge and positive attitude change towards HIV infection and AIDS than maths students. The results showed significant differences between third year nursing students' knowledge about HIV and AIDS when compared with other groups but it was noted that knowledge levels for all groups was quite low. There was no difference between first and third year nursing students' attitudes and moral judgement about HIV and AIDS but there was a significant difference between nursing students and maths students. It was suggested that there is a need to modify nurse education programmes in order to have greater impact on this topic area.

Barriers to effective mental health services for African Americans.

Many African Americans--especially the most marginal--suffer from mental health problems and would benefit from timely access to appropriate forms of care. However, few seek treatment from outpatient providers in the specialty mental health sector and those who do are at risk of dropping out. African Americans visit providers in the general medical sector, although they use another hypothesized alternative to specialty care, voluntary support networks, less than other groups. These help-seeking tendencies may reflect characteristic coping styles and stigma, as well as a lack of resources and opportunities for treatment. More should be learned about differences in need according to location, social standing, and cultural orientation so as to identify treatments and programs that are especially beneficial to African Americans.

Social embeddedness and psychological well-being among African Americans and whites.

Using data from the National Medical Expenditure Survey, a household survey of more than 18,000 respondents, this study examined racial and gender differences in social embeddedness, an indicator of community well-being and social support. The study hypothesized that higher levels of social embeddedness would be found among African Americans than among Whites and that the association between social embeddedness and psychological well-being would be stronger among African Americans than among Whites. African American men reported themselves more socially embedded overall than White men and, in one instance, their social involvement was especially important in predicting psychological well-being. African American women were more likely than White women to report attending meetings of churches and community groups, but otherwise were less socially involved than White women. There was no evidence of a difference between African American and White women in strength of the connection between social embeddedness and psychological well-being. African American social involvement is more selective than previously believed and generalizations must be qualified on the basis of gender.

Ethnic minority populations and mental health outcomes.

This chapter presents a framework for evaluating outcomes from mental health intervention in ethnic minority populations, reviews existing outcomes research, and describes ways to increase the quantity and quality of minority outcomes research.

The peculiar successes of community psychology: service delivery to ethnic minorities and the poor.

The 20-year history of community psychology is considered with respect to activities on behalf of ethnic minority participation in psychotherapy, increasing cultural diversity, and to a considerably lesser extent, enhancing community systems. A discrepancy was found between community psychology in principle and community psychology in practice. For the future, community psychologists are advised to identify and seek to strengthen (a) indigenous resources for solving personal and community problems; and (b) pathways of help seeking followed by community members. Community psychology is encouraged to reclaim and enact more vigorously its own legacy. To do otherwise, it is argued, forfeits development of potentially significant research and practice and risks continued ambivalence and dissatisfaction despite worthwhile contribution--suffering the peculiar successes of community psychology.

Medicaid and African American outpatient mental health treatment.

The present study tested the hypothesis that Medicaid-financed African Americans would be more likely to receive outpatient mental health treatment than African Americans whose treatment was financed by private insurance. The hypothesis was confirmed: when compared with privately insured persons eligible for care under either fee-for-service or managed care, the Black-White gap in outpatient service use was significantly smaller under Medicaid. There was no racial difference in outpatient treatment rates among the uninsured. The often-noted difference between Blacks and Whites in the likelihood of receiving outpatient mental health treatment is confined largely to the privately insured.
