TL;DR: In this article, a community-level theory that builds on Shaw and McKay's original model is formulated and tested, and the model is first tested by analyzing data for 238 localities in Great Britain constructed from a 1982 national survey of 10,905 residents.
Abstract: Shaw and McKay's influential theory of community social disorganization has never been directly tested. To address this, a community-level theory that builds on Shaw and McKay's original model is formulated and tested. The general hypothesis is that low economic status, ethnic heterogeneity, residential mobility, and family disruption lead to community social disorganization, which, in turn, increases crime and delinquency rates. A community's level of social organization is measured in terms of local friendship networks, control of street-corner teenage peer groups, and prevalence of organizational participation. The model is first tested by analyzing data for 238 localities in Great Britain constructed from a 1982 national survey of 10,905 residents. The model is then replicated on an independent national sample of 11,030 residents of 300 British localities in 1984. Results from both surveys support the theory and show that between-community variations in social disorganization transmit much of the effect of community structural characteristics on rates of both criminal victimization and criminal offending.

TL;DR: Evidence is presented in support of the hypothesis that the route to chronic delinquency is marked by a reliable developmental sequence of experiences, which assumes that children following this developmental sequence are at high risk for engaging in chronic delinquent behavior.
Abstract: A developmental model of antisocial behavior is outlined. Recent findings are reviewed that concern the etiology and course of antisocial behavior from early childhood through adolescence. Evidence is presented in support of the hypothesis that the route to chronic delinquency is marked by a reliable developmental sequence of experiences. As a first step, ineffective parenting practices are viewed as determinants for childhood conduct disorders. The general model also takes into account the contextual variables that influence the family interaction process. As a second step, the conduct-disordered behaviors lead to academic failure and peer rejection. These dual failures lead, in turn, to increased risk for depressed mood and involvement in a deviant peer group. This third step usually occurs during later childhood and early adolescence. It is assumed that children following this developmental sequence are at high risk for engaging in chronic delinquent behavior. Finally, implications for prevention and intervention are discussed.

TL;DR: Searches for triple conjunctions (Color X Size X Form) are easier than searches for standard conjunctions and can be independent of set size, and three parallel processes can guide attention more effectively than two.
Abstract: Subjects searched sets of items for targets defined by conjunctions of color and form, color and orientation, or color and size. Set size was varied and reaction times (RT) were measured. For many unpracticed subjects, the slopes of the resulting RT X Set Size functions are too shallow to be consistent with Treisman's feature integration model, which proposes serial, self-terminating search for conjunctions. Searches for triple conjunctions (Color X Size X Form) are easier than searches for standard conjunctions and can be independent of set size. A guided search model similar to Hoffman's (1979) two-stage model can account for these data. In the model, parallel processes use information about simple features to guide attention in the search for conjunctions. Triple conjunctions are found more efficiently than standard conjunctions because three parallel processes can guide attention more effectively than two. Language: en

TL;DR: A proposed revision of the Dollard et al. (1939) frustration-aggression hypothesis holds that frustrations generate aggressive inclinations to the degree that they arouse negative affect.
Abstract: Examines the Dollard et al. (1939) frustration-aggression hypothesis. The original formulation's main proposition is limited to interference with an expected attainment of a desired goal on hostile (emotional) aggression. Although some studies have yielded negative results, others support the core proposition. Frustrations can create aggressive inclinations even when they are not arbitrary or aimed at the subject personally. Interpretations and attributions can be understood partly in terms of the original analysis but they can also influence the unpleasantness of the thwarting. A proposed revision of the 1939 model holds that frustrations generate aggressive inclinations to the degree that they arouse negative affect. Evidence regarding the aggressive consequences of aversive events is reviewed, and Berkowitz's cognitive-neoassociationistic model is summarized. In 1939, researchers at the Yale University Institute of Human Relations published a small monograph that has had a tremendous impact, directly or indirectly, on almost all of the behavioral sciences. Led by,John Dollard, Leonard Doob, Neal Miller, O. H. Mowrer, and Robert Sears (1939), the group attempted to account for virtually all of human aggression with a few basic ideas. Their book, Frustration and Aggression, quickly attracted considerable attention. Seven articles in one 1941 issue of Psychological Review were devoted to the controversy generated by the monograph, and excerpts from these papers as well as from other related articles were reprinted in a major section of the classic Readings in Social Psychology (Newcomb & Hartley, 1947). Most of the studies investigating the causes and consequences of aggression in the immediately following decades were oriented, to some extent at least, toward issues raised by the Yale group's analysis (see Berkowitz, 1958, 1962; Buss, 1961).

TL;DR: Findings from a cohort study show that being abused or neglected as a child increases one's risk for delinquency, adult criminal behavior, and violent criminal behavior; however, the majority of abused and neglected children do not become delinquent, criminal, or violent.
Abstract: Despite widespread belief that violence begets violence, methodological problems substantially restrict knowledge of the long-term consequences of childhood victimization. Empirical evidence for this cycle of violence has been examined. Findings from a cohort study show that being abused or neglected as a child increases one's risk for delinquency, adult criminal behavior, and violent criminal behavior. However, the majority of abused and neglected children do not become delinquent, criminal, or violent. Caveats in interpreting these findings and their implications are discussed in this article.

TL;DR: Risk factors for having a single fall were few and relatively weak, but multiple falls were more predictable, and increased odds of two or more falls for persons who had difficulty standing up from a chair, difficulty performing a tandem walk, arthritis, Parkinson's disease, and a fall with injury during the previous year were found.
Abstract: Falls are a major threat to the health of older persons. We evaluated potential risk factors for falls in 325 community-dwelling persons aged 60 years or older who had fallen during the previous year, then followed up weekly for 1 year to ascertain nonsyncopal falls and their consequences. Risk factors for having a single fall were few and relatively weak, but multiple falls were more predictable. In multivariate analyses, we found increased odds of two or more falls for persons who had difficulty standing up from a chair, difficulty performing a tandem walk, arthritis, Parkinson's disease, three or more falls during the previous year, and a fall with injury during the previous year, and for whites. The proportion of subjects with two or more falls per year increased from 0.10 for those with none or one of these risk factors to 0.69 for those with four or more risk factors. Among older persons with a history of a recent fall, the risk of multiple nonsyncopal falls can be predicted from a few simple questions and examinations. ( JAMA . 1989;261:2663-2668)

TL;DR: T-RTS, the sum of coded values of GCS, SBP, and RR, demonstrated increased sensitivity and some loss in specificity when compared with a triage criterion based on TS and GCS values, and RTS demonstrated substantially improved reliability in outcome predictions compared to the TS.
Abstract: The Trauma Score (TS) has been revised. The revision includes Glasgow Coma Scale (GCS), systolic blood pressure (SBP), and respiratory rate (RR) and excludes capillary refill and respiratory expansion, which were difficult to assess in the field. Two versions of the revised score have been developed, one for triage (T-RTS) and another for use in outcome evaluations and to control for injury severity (RTS). T-RTS, the sum of coded values of GCS, SBP, and RR, demonstrated increased sensitivity and some loss in specificity when compared with a triage criterion based on TS and GCS values. T-RTS correctly identified more than 97% of nonsurvivors as requiring trauma center care. The T-RTS triage criterion does not require summing of the coded values and is more easily implemented than the TS criterion. RTS is a weighted sum of coded variable values. The RTS demonstrated substantially improved reliability in outcome predictions compared to the TS. The RTS also yielded more accurate outcome predictions for patients with serious head injuries than the TS.

TL;DR: Results showed that all the variables measuring the quality of experience, except for relaxation and motivation, are more affected by flow than by whether the respondent is working or in leisure.
Abstract: Followed 78 adult workers for 1 week with the experience sampling method. (This method randomly samples self-reports throughout the day.) The main question was whether the quality of experience was more influenced by whether a person was at work or at leisure or more influenced by whether a person was in flow (i.e., in a condition of high challenges and skills). Results showed that all the variables measuring the quality of experience, except for relaxation and motivation, are more affected by flow than by whether the respondent is working or in leisure. Moreover, the great majority of flow experiences are reported when working, not when in leisure. Regardless of the quality of experience, however, respondents are more motivated in leisure than in work. But individuals more motivated in flow than in apathy reported more positive experiences in work. Results suggest implications for improving the quality of everyday life.

TL;DR: The results suggest that the RAPI may be a useful tool for the standardized and efficient assessment of problem drinking during adolescence.
Abstract: Longitudinal data were obtained from a nonclinical sample of 1,308 male and female adolescents covering the age range from 12 to 21. Factor analyses of 52 symptoms and/or consequences of alcohol use yielded three problem dimensions. In addition, a unidimensional, 23-item scale (the Rutgers Alcohol Problem Index, RAPI) was constructed with an internal consistency of .92. Correlations between RAPI and alcohol-use intensity were moderately strong for all age groups at each test occasion (ranging from .20 to .57), yet low enough to suggest that identification of problem drinkers requires both types of measures. The results suggest that the RAPI may be a useful tool for the standardized and efficient assessment of problem drinking during adolescence.

TL;DR: Factors associated with falls in a community-based prospective study of 761 subjects 70 years and older found decreased levels of physical activity, stroke, arthritis of the knees, impairment of gait, and increased body sway were associated with an increased risk of falls.
Abstract: We investigated factors associated with falls in a community-based prospective study of 761 subjects 70 years and older The group experienced 507 falls during the year of monitoring On entry to the study a number of variables had been assessed in each subject Variables associated with an increased risk of falling differed in men and women In men, decreased levels of physical activity, stroke, arthritis of the knees, impairment of gait, and increased body sway were associated with an increased risk of falls In women, the total number of drugs, psychotropic drugs and drugs liable to cause postural hypotension, standing systolic blood pressure of less than 110 mmHg, and evidence of muscle weakness were also associated with an increased risk of falling Most falls in elderly people are associated with multiple risk factors, many of which are potentially remediable The possible implications of this in diagnosis and prevention are discussed Language: en

TL;DR: It is suggested that reduced central serotonergic function is present in a subgroup of patients with major affective and/or personality disorder and is associated with history of suicide attempt in patients with either disorder, but with impulsive aggression in Patients with personality disorder only.
Abstract: • Dysfunction of the central serotonergic system has been variously associated with depression and with suicidal and/or impulsive aggressive behavior. To evaluate central serotonergic function in relation to these variables, prolactin responses to a singledose challenge with fenfluramine hydrochloride (60 mg orally), a serotonin releasing/uptake-inhibiting agent, were examined in 45 male patients with clearly defined major affective (n = 25) and/or personality disorder (n 20) and in 18 normal male control patients. Prolactin responses to fenfluramine among all patients were reduced compared with responses of controls. Reduced prolactin responses to fenfluramine were correlated with history of suicide attempt in all patients but with clinician and selfreported ratings of impulsive aggression in patients with personality disorder only; there was no correlation with depression. These results suggest that reduced central serotonergic function is present in a subgroup of patients with major affective and/or personality disorder and is associated with history of suicide attempt in patients with either disorder, but with impulsive aggression in patients with personality disorder only.
TL;DR: Most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behaviour and group size, but many studies reveal interesting features of the relationship between Vigilance and Group size that should provide fruitful avenues for future research.
Abstract: One commonly cited benefit to animals that forage in groups is an increase in the probability of detecting a predator, and a decrease in the time spent in predator detection. A mathematical model (Pulliam 1973) predicts a negative relationship between group size and vigilance rates. Over fifty studies of birds and mammals report that the relationship at least partly explains why individuals forage in groups. This review evaluates the strength of these conclusions based on their evidence. Those variables that may confound the relationship between vigilance and group size are outlined, and their control is assessed for each study. The variables I consider to be important include the density and type of food; competition between individuals; the proximity to both a safe place and the observer; the presence of predators; the visibility within the habitat; the composition of the group; the ambient temperature and the time of day. Based on these assessments, most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behavior and group size. Nevertheless, many studies reveal interesting features of the relationship between vigilance and group size that should provide fruitful avenues for future research.
TL;DR: Vertebral fracture prevalence was assessed in an age-stratified random sample of Rochester, Minnesota women aged 50 years and over, finding that vertebral fractures were common and increased with age.
Abstract: Vertebral fracture prevalence was assessed in an age-stratified random sample of Rochester, Minnesota women aged 50 years and over. Vertebral fractures, including wedge and concavity as well as compression fractures, were common and increased with age. The estimated incidence of new vertebral fractures also rose with age, reaching 29.6 per 1,000 person-years in women aged greater than or equal to 85 years. The prevalence of one or more vertebral fractures also increased with declining bone mass, reaching 42% in women with spinal bone mineral density less than 0.6 g/cm2 by dual photon absorptiometry. Bone mass and age contributed independently to the risk of vertebral fracture, but "age" may reflect other manifestations of osteoporosis.
TL;DR: The annual incidence of falls among elderly persons living in the community increases from 25 percent at 70 years of age to 35 percent after 75 years ofAge, and in nursing homes, where the average annual incidence is 1600 per 1000 patients.
Abstract: THE annual incidence of falls among elderly persons living in the community increases from 25 percent at 70 years of age to 35 percent after 75 years of age.1 Fifty percent of elderly persons who fall do so repeatedly. Falls are even more common in nursing homes, where the average annual incidence of reported falls is 1600 per 1000 patients.2 Women fall more often than men until the age of 75 years, after which the frequency is similar in both sexes.1 In the statistics reported here, and in the field of geriatrics generally, "falls" excludes those that result from major . . .
TL;DR: Trends in cohort changes are evident in the United States, Sweden, Germany, Canada, and New Zealand, but not in comparable studies conducted in Korea and Puerto Rico and of Mexican-Americans living in theUnited States.
Abstract: Several recent, large epidemiologic and family studies suggest important temporal changes in the rates of major depression: an increase in the rates in the cohorts born after World War II; a decrease in the age of onset with an increase in the late teenaged and early adult years; an increase between 1960 and 1975 in the rates of depression for all ages; a persistent gender effect, with the risk of depression consistently two to three times higher among women than men across all adult ages; a persistent family effect, with the risk about two to three times higher in first-degree relatives as compared with controls; and the suggestion of a narrowing of the differential risk to men and women due to a greater increase in risk of depression among young men These trends, drawn from studies using comparable methods and modern diagnostic criteria, are evident in the United States, Sweden, Germany, Canada, and New Zealand, but not in comparable studies conducted in Korea and Puerto Rico and of MexicanAmericans living in the United States These cohort changes cannot be fully attributed to artifacts of reporting, recall, mortality, or labeling and have implications for understanding the etiology of depression and for clinical practice (JAMA 1989;261:2229-2235)
TL;DR: It is concluded that bicycle safety helmets are highly effective in preventing head injury, particularly important for children, since they suffer the majority of serious head injuries from bicycling accidents.
Abstract: Bicycling accidents cause many serious injuries and, in the United States, about 1300 deaths per year, mainly from head injuries. Safety helmets are widely recommended for cyclists, but convincing evidence of their effectiveness is lacking. Over one year we conducted a case-control study in which the case patients were 235 persons with head injuries received while bicycling, who sought emergency care at one of five hospitals. One control group consisted of 433 persons who received emergency care at the same hospitals for bicycling injuries not involving the head. A second control group consisted of 558 members of a large health maintenance organization who had had bicycling accidents during the previous year. Seven percent of the case patients were wearing helmets at the time of their head injuries, as compared with 24 percent of the emergency room controls and 23 percent of the second control group. Of the 99 cyclists with serious brain injury only 4 percent wore helmets. In regression analyses to control for age, sex, income, education, cycling experience, and the severity of the accident, we found that riders with helmets had an 85 percent reduction in their risk of head injury (odds ratio, 0.15; 95 percent confidence interval, 0.07 to 0.29) and an 88 percent reduction in their risk of brain injury (odds ratio, 0.12; 95 percent confidence interval, 0.04 to 0.40). We conclude that bicycle safety helmets are highly effective in preventing head injury. Helmets are particularly important for children, since they suffer the majority of serious head injuries from bicycling accidents.
TL;DR: This article presents a comprehensive review of empirical studies of sex offender recidivism, bringing together data from a wide variety of studies on both treated and untreated sex offenders of all types.
Abstract: The increasing recognition of the large number of people victimized by sexual assault has focused considerable attention on methods for deterring its perpetrators. In particular, law enforcement and mental health professions alike seek ways to prevent sex offenders from repeating their criminal behavior. Some evidence suggests sex offenders often continue offending even after incarceration or clinical treatment. However, recidivism rates for sex offenders are unusually hard to establish, owing to gross underreporting of sex crimes. This article presents a comprehensive review of empirical studies of sex offender recidivism. It brings together data from a wide variety of studies on both treated and untreated sex offenders of all types. Because of the variety and gravity of methodological problems in these studies, guidelines are discussed for sample selection and description, study design, criterion assessment, and data analysis. With these methodological principles in mind, the results of some 42 studies are examined for what they can tell us about sex offender recidivism and efforts to reduce it.
TL;DR: Data suggest that the TSC-33 and its associated subscales are reasonably reliable measures that display some predictive and discriminative validity with regard to childhood sexual abuse.
Abstract: A 33-item Trauma Symptom Checklist (TSC-33) is presented, and the psychometric properties of this scale are summarized from four separate studies. Developed to assess the impact of childhood abuse on later (adult) functioning, the TSC-33 consists of five subscales (Dissociation, Anxiety, Depression, Post-Sexual Abuse Trauma-hypothesized [PSAT-h], and Sleep Disturbance) and a total scale score. Data suggest that the TSC-33 and its associated subscales are reasonably reliable measures that display some predictive and discriminative validity with regard to childhood sexual abuse. Other variables appear to elevate checklist scores as well, however, such as physical abuse history and mental health client status, although apparently not gender.
TL;DR: It is apparent from this study that seasonal affective disorder represents the extreme end of the spectrum of seasonality that affects a large percentage of the general population and might provide valuable insight into pathogenesis, treatment, and prevention of affective illness.
Abstract: Patterns of seasonal changes in mood and behavior in Montgomery County, Maryland, were evaluated in randomly selected household samples by lay interviewers using a telephone version of the Seasonal Pattern Assessment Questionnaire. The method for selecting the sample unit was random-digit dialing. We found that 92% of the survey subjects noticed seasonal changes of mood and behavior to varying degrees. For 27% of the sample seasonal changes were a problem and 4.3% to 10% of subjects, depending on the case-finding definition, rated a degree of seasonal impairment equivalent to that of patients with seasonal affective disorder. The seasonal pattern of "feeling worst" exhibited a bimodal distribution with a greater winter and a substantially lower summer peak (ratio, 4.5:1). Younger women who have a problem with seasonal changes and who feel worse on short days tended to exhibit the highest seasonality scores. It is apparent from our study that seasonal affective disorder represents the extreme end of the spectrum of seasonality that affects a large percentage of the general population. The influence of environmental factors on mood disorders and mood changes in the general population might provide valuable insight into pathogenesis, treatment, and prevention of affective illness.
TL;DR: Conditional probability analyses indicated that the likelihood of physically aggressing at 30 months given that one had engaged in such aggression before marriage and at 18 months after marriage was .72 for women and .59 for men.
Abstract: Community couples (N = 272) were assessed in a longitudinal study of early marriage. More women than men reported physically aggressing against their partners at premarriage (44% vs. 31%) and 18 months (36% vs. 27%). At 30 months, men and women did not report significantly different rates of aggression (32% vs. 25%). However, using either the self-report or the partner's report, the prevalence of aggression was higher for women than men at each assessment period. Modal forms of physical aggression for both men and women were pushing, shoving, and slapping. Conditional probability analyses indicated that the likelihood of physically aggressing at 30 months given that one had engaged in such aggression before marriage and at 18 months after marriage was .72 for women and .59 for men. Furthermore, 25-30% of the recipients of physical aggression at all three assessment periods were seriously maritally discordant at 30 months.
TL;DR: Data support the concept of performing focused fall risk assessments to identify elderly patients at high risk for falling and develop a fall prediction model from these findings.
Abstract: • A study was performed to identify and rank risk factors for falling among populations of institutionalized (fallers, N=79, nonfallers, N=70) and noninstitutionalized (fallers, N =34, nonfallers, N = 34) elderly persons. Fallers were matched by age, sex, and living location to nonfaller control subjects. A nurse practitioner performed a comprehensive physical assessment in all subjects using a standardized protocol and physician consultation. Fallers in both populations were significantly more physically and functionally impaired than control subjects. Logistic regression identified hip weakness, poor balance, and number of prescribed medications as factors most strongly associated with falling among institutionalized subjects. A fall prediction model was developed from these findings yielding 76% overall predictive accuracy (89% sensitivity, 60% specificity). Using the model, the predicted 1-year risk of falling ranged from 12% for persons with none of the three risk factors to 100% for persons with all three risk factors. Findings among noninstitutionalized subjects were similar. These data support the concept of performing focused fall risk assessments to identify elderly patients at high risk for falling.

TL;DR: The effects of automobile accidents on seat belt use, criminal victimization other than rape on individual crime prevention efforts, natural hazards experience on both natural hazards preparedness and compliance with evacuation warnings, and myocardial infarction on smoking are reviewed.
Abstract: This article seeks to further our understanding of self-protective behavior by examining the effects of a particularly powerful stimulus to action: personal experience. It reviews the effects of automobile accidents on seat belt use, criminal victimization other than rape on individual crime prevention efforts, natural hazards experience on both natural hazards preparedness and compliance with evacuation warnings, and myocardial infarction on smoking. Theories suggesting mechanisms that could link personal experience to behavior are described, and data concerning the effects of experience on some key variables in these theories are discussed. Tentative propositions are offered to resolve the many apparent discrepancies in this literature. These propositions concern the effects of experience on risk perceptions, the influence of experience on risk salience, the specificity of responses to victimization, and the duration of experience effects.
TL;DR: Results show that five of seven expectancy scores readily discriminated between nonproblem drinkers and those subsequently beginning problem drinking and accounted for a large portion of the variance in a continuous quantity/frequency index and a problem drinking index.
Abstract: An accumulating literature has shown the influence of childhood experiences associated with alcohol use on later drinking practices. Recent studies have suggested that alcohol-related expectancy may serve as an intervening variable to connect these early experiences with the later, proximal decision to drink when opportunities for actual alcohol consumption arise. Those studies, however, have collected expectancy and drinking data concurrently, whereas the present study for the first time reports on the power of expectancies measured in early adolescents (seventh and eighth grades) to predict self-reported drinking onset and drinking behavior measured a full year later. Results show that five of seven expectancy scores readily discriminated between nonproblem drinkers and those subsequently beginning problem drinking and accounted for a large portion of the variance in a continuous quantity/frequency index and a problem drinking index. The strength of these timelagged relations strengthens the case for inferring that expectancies have causal power on drinking behavior and suggests prevention strategies.
TL;DR: Results indicate that when the harm-doers apologized, as opposed to when they did not, the victim-subjects refrained from severe aggression against them.
Abstract: Two studies examined the effects of an apology on a victim's aggression and explored the psychological mechanisms underlying such effects. In Study 1, female undergraduates were psychologically harmed and then received an apology by another female student. In Study 2, male undergraduates were asked to role play a victim in a hypothetical harm situation. Results indicate that when the harm-doers apologized, as opposed to when they did not, the victim-subjects refrained from severe aggression against them. Regression analyses suggested that such aggression-inhibitory effects of an apology were mediated by impression improvement, emotional mitigation, and reduction in desire for an apology within the victims. It was also found that when the harm was severe, such effects of an apology on aggression were attenuated. The more severe the harm is, the more extensive of an apology may be needed to alleviate the victim's anger and aggression.
TL;DR: It is concluded that panic disorder and attacks are associated with an increased risk of suicidal ideation and suicide attempts, and Physicians working in general medical settings and emergency departments should be alert to this problem.
Abstract: Panic disorder, which is found in about 1.5 percent of the population at some time in their lives, includes recurrent episodes of sudden, unpredictable, intense fear accompanied by symptoms such as palpitations, chest pain, and faintness. Panic attacks, which do not meet these diagnostic criteria fully, are two to three times more prevalent. Since panic symptoms can mimic those of other medical disorders, patients with these symptoms use medical services frequently. To determine the risk of suicidal ideation and suicide attempts in panic disorder and attacks, we studied a random sample of 18,011 adults drawn from five U.S. communities. Subjects who had panic disorder, as compared with other psychiatric disorders, had more suicidal ideation and suicide attempts, with an adjusted odds ratio for suicide attempts of 2.62 (95 percent confidence interval, 1.83 to 3.74). The odds ratio was 17.99 (95 percent confidence interval, 12.18 to 26.58) when the group with panic disorder was compared with subjects who had no psychiatric disorder. Twenty percent of the subjects with panic disorder and 12 percent of those with panic attacks had made suicide attempts. These results could not be explained by the coexistence of major depression or of alcohol or drug abuse. We conclude that panic disorder and attacks are associated with an increased risk of suicidal ideation and suicide attempts. Physicians working in general medical settings and emergency departments should be alert to this problem.
TL;DR: In this article, the authors argue that existing delinquency theories are fundamentally inadequate to the task of explaining female delinquency and official reactions to girls' deviance, and they suggest that the official actions of the juvenile justice system should be understood as major forces in women's oppression as they have historically served to reinforce the obedience.
Abstract: This article argues that existing delinquency theories are fundamentally inadequate to the task of explaining female delinquency and official reactions to girls' deviance. To establish this, the article first reviews the degree of the androcentric bias in the major theories of delinquent behavior. Then the need for a feminist model of female delinquency is explored by reviewing the available evidence on girls' offending. This review shows that the extensive focus on disadvantaged males in public settings has meant that girls' victimization and the relationship between that experience and girls' crime has been systematically ignored. Also missed has been the central role played by the juvenile justice system in the sexualization of female delinquency and the criminalization of girls' survival strategies. Finally, it will be suggested that the official actions of the juvenile justice system should be understood as major forces in women's oppression as they have historically served to reinforce the obedience...
TL;DR: The vast majority of sexually victimized women (75-91%) could not be differentiated from nonvictims, and the concept of traumatic sexualization was used to explain this finding.
Abstract: Examined the accuracy with which rape and lesser sexual assaults were predicted among a representative national sample of 2,723 college women. A total of 14 risk variables operationalized three vulnerability hypotheses: (a) vulnerability-creating traumatic experiences, (b) social-psychological vulnerability, and (c) vulnerability-enhancing situations. Each hypothesis was tested individually, and a composite model was developed via discriminant analysis. Only the traumatic experiences variables clearly improved over the base rates in identifying rape victims, but risk variables from each vulnerability hypothesis met criteria for inclusion in the composite model. A risk profile emerged that characterized only 10% of the women, but among them the risk of rape was twice the rate of women without the profile. The concept of traumatic sexualization was used to explain this finding. However, the vast majority of sexually victimized women (75-91%) could not be differentiated from nonvictims.
TL;DR: The box plot is applied to tabular data from two recently published articles to show how readers can use box plots to improve the interpretation of data in complex tables and recommend that the box plot be used more frequently.
Abstract: Exploratory data analysis involves the use of statistical techniques to identify patterns that may be hidden in a group of numbers. One of these techniques is the "box plot," which is used to visually summarize and compare groups of data. The box plot uses the median, the approximate quartiles, and the lowest and highest data points to convey the level, spread, and symmetry of a distribution of data values. It can also be easily refined to identify outlier data values and can be easily constructed by hand. We apply box plots to tabular data from two recently published articles to show how readers can use box plots to improve the interpretation of data in complex tables. The box plot, like other visual methods, is more than a substitute for a table: It is a tool that can improve our reasoning about quantitative information. We recommend that the box plot be used more frequently.
TL;DR: Children's self-concepts of ability for math and English became less stable across the junior high transition, whereas beliefs about other activities and general self-esteem were more stable in seventh grade.
Abstract: We assessed how children's self-concepts of ability for mathematics, English, social, and physical skills activities, ratings of the importance of these activities, and general self-esteem change across the transition to junior high school. Three types of change were assessed: change in mean levels, change in stability, and change in relationships. Twice each year during the sixth and seventh grades, 1,450 children completed questionnaires. Mean levels of children's self-esteem were lowest immediately after the transition, but recovered during seventh grade. Self-concept of ability and importance ratings for math and sports activities showed linear declines. Self-concept of ability for social activities showed a cubic trend, but importance ratings for social activities declined in a linear fashion. Children's self-concepts of ability for math and English became less stable across the junior high transition, whereas beliefs about other activities and general self-esteem were more stable in seventh grade.
TL;DR: Nicotine in patients with dementia of the Alzheimer type (DAT) producted a significant and marked improvement in discriminative sensitivity and reaction times on a computerised test of attention and information processing.
Abstract: Nicotine in patients with dementia of the Alzheimer type (DAT) produced a significant and marked improvement in discriminative sensitivity and reaction times on a computerised test of attention and information processing. Nicotine also improved the ability of DAT patients to detect a flickering light in a critical flicker fusion test. These results suggest that nicotine may be acting on cortical mechanisms involved in visual perception and attention, and support the hypothesis that acetylcholine transmission modulates vigilance and discrimination. Nicotine may therefore be of some value in treating deficits in attention and information processing in DAT patients.
