Letter from Jay Reed regarding Dickinson Pool Halls, September 1919
September 4, 1919, letter from Jay Reed, President of the Reed Brothers Department Store in Dickinson, North Dakota, to Attorney General William Langer regarding several pool halls in that town. Reed remarks that the local police are unable to get on the inside and asks that Langer\u27s undercover investigators (known as Flying Squadrons ) take on the case.https://commons.und.edu/langer-papers/1335/thumbnail.jp
Analysis of the Function and Evolution of Mite Pockets in Lizards.
Numerous lizard species possess mite pockets – dermal invaginations inhabited by ectoparasitic mites, particularly chiggers (Trombiculidae, Leeuwenhoekiidae). Pockets shelter mites, and chiggers preferentially attach within pockets. However, it remains unclear how lizards benefit from this association. In the present study, associations between mites, pockets, and hosts in the Phrynosomatidae were examined using phylogenetically-independent comparative methods and ancestral state reconstructions, and hypotheses for pocket function experimentally tested using Sceloporus jarrovi (Phrynosomatidae).
Mite infestations in S. jarrovi varied greatly between host demographic groups. Chiggers concentrated within the nuchal pocket in all groups, and pocket capacity was limited by host body size. Ectoparasitism significantly impaired growth in juveniles but had no effect on adult body condition.
Examination of museum specimens representing 77 phrynosomatid species revealed similar patterns of ectoparasitism. Nuchal pockets occurred in 70 species; post-inguinal pockets in only 14. Chiggers consistently concentrated in the pockets despite variation in host species morphology and ecology. Comparative analysis revealed mite loads to be positively correlated with pocket size and habitat, and negatively with latitude. Pocket morphology varied considerably, displaying significant positive associations with body size and rugosity, and negative with latitude.
Damage-amelioration and mate choice hypotheses for pocket function were experimentally tested using S. jarrovi. Damage-amelioration proposes pockets reduce and/or repair mite damage. Histomorphometric analyses indicate pocket tissues differ morphologically from non-pockets but do not reduce or rapidly repair damage. Instead, pockets likely reduce mite feeding efficiency and/or reduce host irritation by limiting mite damage to the superficial tissues.
The mate choice hypothesis proposes pockets conceal ectoparasites from conspecifics. In mate choice trials female S. jarrovi appeared to choose males randomly; neither ectoparasite burden nor male morphology had a significant influence on female choice, and the mate choice hypothesis was not supported.
Ancestral state reconstructions suggest the ancestor of Phrynosomatidae had small nuchal pockets, no post-inguinal pockets, and modest mite loads. Nuchal pockets were independently lost in Callisaurini and Uta, possibly due to specialization for arid habitats. Expansion and diversification of Sceloporus into moist, low latitude, high elevation habitats with dense mite populations coincided with enlargement of nuchal pockets, suggestive of mite-related function.PHDEcology and Evolutionary BiologyUniversity of Michigan, Horace H.

Regional Development: An Econometric Study of the Role of Water Development in Effectuating Population and Income Changes
Twelve measures of regional economic growth, including populations and three measures of income were compared for areas with and without water investment in 246 counties and 42 water resources subareas in the states of Utah, Colorado, New Mexico, Montana, Wyoming, Idaho, and Nevada. Simple mean omparisons for these measures compiled for the decades of 1940-1950, 1950-1960, and 1960-1970 failed to support the hypothesis that economic growth of those counties and subareas receiving water investment was significantly highter than in those areas which did not, with the possible exception of the 1940-1950 decade. This result is obciously tempered by the fact that with-without comparisons taken on a cross-sectional basis may be inaccurage to the extent that spatial units used in the analysis are not homogenous in all respects but the presence or absence of water investment. Population, farm income, median family income, and per acre agricultural land values as measures of economic growth were regressed on various classes of water investment (Total, M&1, Recreation, and Irrigation investment, and other related variables) for the spatial units. Results obtained from this analysis were inconclusive with respect to the hypothesized role of water investment in effectuating economic growth. For small areas in New Mexico where more detailed records of water investment were available, a nine equation econometric model was estimated using a three-stage least squares analysis. As specified, this model facilitated an examination of the interactive effect of water development as a causal variable and as an endogenous variable which responds to other growth inducements. Test statistics for multi-equation systems are only indicative, and the statistical results were nonconclusive, although expected signs on the coefficients were obtained in most instances. Input-output and economic base-models were used to examine two case studies of water investment in Western Coloado. The objective was to demonstrate the methodology and the magnitudes of change in regional economic activity (gross regional output, exports, income, and employment) which could be associated with major irrigation-type water developments. In this analysis it was found that total gross output attributable to the projects ranged from zero in the petroleum and mining sectors to a high of 260,302 in the dairy industry. Multiplicative effects on employment income and gross economic activity ranged from 1.06 to 2.30 times their initial magnitude. Income and employment multipliers were of similar magnitude. it should be recognized that these estimates cannot e viewed in the same manner as similar growth increments at the national level, as would typically be done, because of the strong possibility of regional offsets occurring in other regions not participating in water development. To the extent that growth in other areas is reduced by the growth of a particular region, these reductions should be subtracted from the growth measured in the latter set of regions. In all tests conducted no conclusive evidence was found taht water development causes regions to grow faster than those regions which did not receive water investment. This is not to say that growth in those regions receiving water investment was not higher than it would have been had the investment not been made. However, it does provide evidence that, an average among the regions included within this analysis, that those areas which did not receive major water investments grow at a faster rate than those which did. Thus, the input-output approach shows potential inpacts from water investment in a general equilibrium context, but rest son the assumption that other concurrent events which could produce similar or offsetting effects in the region are held constant. The cross-section analysis measures total changes in a regional economy overtime, but the multiplicity of events, other than water investment, may obscure the effects of water investment
Multi-person sex among a sample of adolescent female urban health clinic patients
Adolescent sexual activity involving three or more people is an emerging public health concern. The goal of this exploratory, cross-sectional study was to describe the prevalence, correlates, and context of multiple-person sex among a sample of adolescent females seeking health care from an urban clinic. Because sex involving multiple people may either be consensual (i.e., “three-ways” or “group sex”) or forced (i.e., “gang rape”), we use the term “multi-person sex” (MPS) to encompass these experiences. Subjects were 328 females, ages 14–20 years old, who utilized a Boston-area community- or school-based health clinic between April and December of 2006, and completed an anonymous survey using computer-assisted self-interview software. Overall, 7.3% reported ever having had a MPS experience. Of these, 52% reported ever being pressured to engage in MPS and 43% reported ever being threatened or forced. Condom nonuse by at least one male participant in the most recent MPS was reported by 45%. Controlling for potential demographic confounders, MPS was associated with cigarette smoking (adjusted prevalence ratio [APR], 3.83; 95% confidence interval [CI], 1.56–9.44), sexual initiation prior to age 15 (APR, 2.50; 95% CI, 1.04–5.98), ever being diagnosed with an STI (APR, 2.55; 95% CI, 1.08–6.03), dating violence victimization (APR, 4.43; 95% CI, 1.68–11.69), childhood sexual abuse victimization (APR, 4.30; 95% CI, 1.83–10.07) and past-month pornography exposure (APR, 4.79; 95% CI, 1.91–11.98). Additional study of the perpetration and prevention of adolescent MPS is urgently needed
A mediation analysis of the role of girl child marriage in the relationship between proximity to conflict and past-year intimate partner violence in post-conflict Sri Lanka
Background Studies from many contexts indicate that proximity to conflict is associated with increased likelihood of intimate partner violence (IPV), and girl child marriage is associated with both proximity to conflict and increased IPV. In this study, we consider whether girl child marriage acts as a mediator of the association between proximity to conflict and IPV in the context of Sri Lanka, which sustained long-term conflict until 2009. Methods We analyzed responses of currently partnered women between ages 18 and 49 in the 2016 Sri Lankan Demographic and Health Survey (N = 13,691). Using logistic regression analyses, we measured associations between proximity to conflict (residence in districts which were central, proximal, or distal to the regions where the war occurred) and the outcomes of IPV and girl child marriage, and secondarily assessed girl child marriage as a possible mediator of the association between proximity to conflict and past year IPV. Results Women residing in districts central to conflict, as compared to districts distal to conflict, had increased odds of past year sexual, physical, and emotional IPV, with the odds of sexual IPV increasing the most (adjusted odds ratio/aOR 4.19, 95% confidence interval/CI 2.08–8.41). Residing in districts proximal to conflict compared to those distal to conflict was associated with lower odds of past year physical and emotional IPV, with the greatest decrease in emotional IPV (aOR 0.31, CI 0.18–0.54). Girl child marriage was more likely in districts central to conflict as opposed to those distal to conflict (aOR 1.89, CI 1.22–2.93), and partially mediated the relationship between centrality to conflict and IPV. Conclusions Our findings demonstrate that residing in districts central to conflict compared to those distal to conflict is associated with greater odds of IPV and girl child marriage in post-conflict Sri Lanka, with girl child marriage partially mediating the association between centrality to conflict and IPV. Residence in districts proximal to conflict appears protective against IPV. Future research should investigate what factors are responsible for decreased IPV in districts proximal to violence, and whether these factors can be reproduced to mitigate the increased prevalence of IPV in districts central to conflict
Does Proximity to Conflict Zones Moderate Associations Between Girl Child Marriage, Intimate Partner Violence, and Contraception in Postconflict Sri Lanka?
Women’s primary contraceptive method type is impacted by the gender inequities of girl child marriage and intimate partner violence (IPV). Outside of South Asia, proximity to conflict zones has been found to impact contraceptive use, girl child marriage, and IPV, possibly moderating associations between these variables. We created multinomial regression models using the 2016 Demographic and Health Survey data from postconflict Sri Lanka to study associations between primary contraceptive method type (modern spacing methods, sterilization, and traditional methods compared to no method) and the gender inequities of girl child marriage and past year sexual, physical, and emotional IPV and to assess whether and how these associations were moderated by proximity to conflict. We found that proximity to conflict moderated the relationships between girl child marriage, past year physical and emotional IPV, and primary contraceptive method type. Girl child marriage was associated with increased relative risk (RR) of modern spacing methods (adjusted RR ratio/aRRR: 1.81–2.21) across all levels of proximity to conflict. In districts distal to conflict, past year physical IPV was associated with decreased RR of sterilization (aRRR: 0.67) and traditional methods (aRRR: 0.63), and past year emotional IPV was associated with decreased RR of traditional methods (aRRR: 0.71). In districts central to conflict, past year emotional IPV was associated with increased RR of modern spacing methods (aRRR: 1.50). Our findings suggest that policymakers and providers who seek to improve reproductive health in Sri Lanka must consider the moderating impact of proximity to conflict on the relationship between contraceptive use and the gender inequities of girl child marriage and IPV
