The Extracurriculum of Two Black Preachers: A Descriptive Study of Culturally Learned Practices

This study examines the "extracurriculum" of the black preacher, the extracurriculum as theorized in Rhetoric & Composition, a subfield within the discipline of English. The extracurriculum is a concept characterized by one scholar (Anne R. Gere) as the various ways people learn to write outside the walls of the academy by forming their own community groups, workshops, and clubs for the purposes of improving writing, making a difference in one's community, and creating opportunities for self-publishing. Along these lines, in studying the literacy traditions in black churches, another scholar (Beverly J. Moss) makes a case for valuing a different kind of text, a text collaboratively authored by congregation and preacher working together--and therefore, in one sense, a community text: the black sermon. This authorship results in the dialogue that the congregation gives to the preacher during delivery, and she/he depends upon that resource, "without whom the sermon event would be impossible," as explained by Henry Mitchell in Black Preaching: The Recovery of a Powerful Art (112-13). Thus, I seek to demonstrate how written and oral texts, primarily sermons, get learned elsewhere, acquired tacitly through such informal ways as merely growing up inside the lived discursive practices of a community; the sometimes (but not always) intentional modeling of predecessors, elders, and mentors; the everyday transmission of verbal customs from one generation to the next, and so on. My investigation centers upon the following question: What literacy practices of the black preacher originated in the extracurriculum of her/his training, and do those practices have any pedagogical implications for writing, particularly for college students who witness those practices in their daily lives? To acquire the qualitative data needed to understand this extracurriculum, I selected two predominantly (though not exclusively) local African American churches. I conducted oral interviews with twelve subjects in this study; six from each congregation, and the interviews were recorded. The subject population consisted of the following: 1) Two preachers (male and female) from two denominations (Baptist & Methodist), each of whom possesses formally certified training or degreed education, as well as at least ten years in the pulpit; 2) Four parishioners (from each congregation), two of whom were recommended by the pastor, and two of whom were randomly selected (parishioners must represent different age groups and genders, and must be active churchgoers; 3) Two personal witnesses, one from each church, who provided insight about the preacher's development. Also, I conducted participant-observations in order to give a full description of the black church environment and the black preacher's congregation, the audience. Additionally, I collected audio-visual recordings of observed worship services. This description and analysis will give a rich account for the complex interplay of the communally learned elements crucial to the black preacher's effectiveness. Therefore, examining the extracurriculum of the black preacher may reveal culturally-specific rhetorical acts that have yet to be adequately examined in the context of writing instruction

Emoticon convergence in Internet chat rooms

The present study examines sex and age differences in the use of emoticons (graphic representations of facial expressions) in Internet chat rooms. Data were collected from four Noesis chat rooms (‘18 plus’, ‘30-something’, ‘40- something’ and ‘50 plus’). Although women were more likely than men to use emoticons, there was no difference between the sexes in the range of emoticons used. The fact that men expressed a similar range of emoticons to women implies a general convergence towards female expression in mixed-sex communication contexts. Chat room users without a profile picture were also more likely to use winking emoticons. This may be because these types of emoticons are more flirtatious in intent, and it is easier for chatters to engage in risky communications when they are less identifiable. Furthermore, age had little bearing on the uptake of emoticons as well as the types of emoticons expressed. We draw upon Communication Accommodation Theory to help explain why emotional expression may converge in the chat room context

Problematic shopping behavior: an item response theory examination of the seven-item bergen shopping addiction scale

There has been an increasing amount of research examining problematic shopping behavior (PSB), often referred to in the psychological literature as “compulsive buying” or “shopping addiction.” A popular scale for assessing the risk of PSB is the seven-item Bergen Shopping Addiction Scale (BSAS). To expand our knowledge of the psychometric properties of this instrument, the present study employed Item Response Theory (IRT) and differential item functioning analyses (DIF) while concurrently attempting to determine a preliminary cut-off point. A relatively large community sample completed the BSAS online (N = 968, Mage = 29.5 years, SDage = 9.36, 32.5% women). IRT analyses showed differences regarding the BSAS items’ discrimination, difficulty, and precision, with a raw score exceeding 23 (out of 28) indicating a higher risk of shopping addiction. Finally, while most BSAS items operated equally among males and females, Item 2 (mood modification) required a higher level of shopping addiction behaviors to be endorsed by males. The BSAS functions as a reliable assessment of the risk of shopping addiction, particularly between average and high levels of the trait. Clinical implications are discussed in light of these findings

Up-dating: ratings of perceived dating success are better online than offline

The primary aims of this study were to test whether perceived dating success would differ between offline and online zero-acquaintance dating contexts, and to investigate the role that self-esteem might play in these evaluations. Participants were presented with the same photos of targets in either an offline or online dating scenario and rated their chances of dating success along with their perceptions of how attractive they thought the target would consider them. Higher self-esteem individuals believed they would be rated as more attractive. There was an overall perception that, irrespective of self-esteem level, meeting online would lead to better chances of dating success. These findings are considered in relation to an increased ability to more precisely manage impressions and develop an image of the self which would be evaluated more positively online

Diet-sourced carbon-based nanoparticles induce lipid alterations in tissues of zebrafish (Danio rerio) with genomic hypermethylation changes in brain

With rising environmental levels of carbon-based nanoparticles (CBNs), there is an urgent need to develop an understanding of their biological effects in order to generate appropriate risk assessment strategies. Herein, we exposed zebrafish via their diet to one of four different CBNs: C60 fullerene (C60), single-walled carbon nanotubes (SWCNT), short multi-walled carbon nanotubes (MWCNTs) or long MWCNTs. Lipid alterations in male and female zebrafish were explored post-exposure in three target tissues (brain, gonads and gastrointestinal tract) using ‘omic’ procedures based in liquid chromatography coupled with mass spectrometry (LC-MS) data files. These tissues were chosen as they are often target tissues following environmental exposure. Marked alterations in lipid species are noted in all three tissues. To further explore CBN-induced brain alterations, Raman microspectroscopy analysis of lipid extracts was conducted. Marked lipid alterations are observed with males responding differently to females; in addition, there also appears to be consistent elevations in global genomic methylation. This latter observation is most profound in female zebrafish brain tissues post-exposure to short MWCNTs or SWCNTs (P < 0.05). This study demonstrates that even at low levels, CBNs are capable of inducing significant cellular and genomic modifications in a range of tissues. Such alterations could result in modified susceptibility to other influences such as environmental exposures, pathology and, in the case of brain, developmental alterations

A Surgical Cryoprobe for Targeted Transcorneal Freezing and Endothelial Cell Removal

PURPOSE: To examine the effects of transcorneal freezing using a new cryoprobe designed for corneal endothelial surgery. METHODS: A freezing console employing nitrous oxide as a cryogen was used to cool a series of different cryoprobe tip designs made of silver for high thermal conductivity. In vitro studies were conducted on 426 porcine corneas, followed by preliminary in vivo investigations on three rabbit corneas. RESULTS: The corneal epithelium was destroyed by transcorneal freezing, as expected; however, the epithelial basement membrane remained intact. Reproducible endothelial damage was optimally achieved using a 3.4 mm diameter cryoprobe with a concave tip profile. Stromal edema was seen in the pre-Descemet's area 24 hrs postfreeze injury, but this had been resolved by 10 days postfreeze. A normal collagen fibril structure was seen 1 month postfreeze, concurrent with endothelial cell repopulation. CONCLUSIONS: Transcorneal freezing induces transient posterior stromal edema and some residual deep stromal haze but leaves the epithelial basement membrane intact, which is likely to be important for corneal re-epithelialization. Localized destruction of the endothelial monolayer was achieved in a consistent manner with a 3.4 mm diameter/concave profile cryoprobe and represents a potentially useful approach to remove dysfunctional corneal endothelial cells from corneas with endothelial dysfunction

TACKoMesh – A randomised controlled trial comparing absorbable versus non-absorbable tack fixation in laparoscopic IPOM + repair of primary incisional hernia using post-operative pain and quality of life - Reliatack™ versus Protack™

There is a clinical need to better understand and improve post-operative pain for patients undergoing laparoscopic repair of incisional hernia. The aim of this single-centre, double-blind, randomised controlled trial was to compare post-operative pain between absorbable and non-absorbable tack fixation in patients undergoing IPOM + repair. Patients with primary incisional hernia (size 3–10 cm), were randomised to either Reliatack™ (n = 27), an articulating-arm device deploying absorbable polymer tacks, or Protack™ (n = 36), a straight-arm device deploying permanent titanium tacks. The primary outcome was reported pain on activity using a visual analogue scale at post-operative day 30. Clinical and patient-reported outcome measures (PROMs) were assessed pre-operatively (day 0), and at 1-, 6-, 30- and 365-days post-surgery. No significant differences in reported pain ‘on activity’ were found at any timepoint. Less reported pain ‘at rest’ was found on post-operative day-1 with absorbable tacks (p = 0.020). Significantly longer mesh-fixation time (p < 0.001) and the use of more knots for fascial closure (p = 0.006) and tacks for mesh-fixation (p = 0.001) were found for the absorbable tack group. There were no differences in other clinical and PROMs between groups. For the whole trial cohort (n = 63) several domains in the Short-Form-36 showed a reduction from baseline scores at day 30 that improved at day 365. At post-operative day 30, 75.0% of patients reported ‘a lot of pain’ since discharge. This study found no difference in reported pain when choosing absorbable or non-absorbable tack fixation. The utility of “early” post-operative pain assessment as a comparator following incisional hernia repair needs clarification

Prevalence of violent advertisements in New York City subways

Background: Media advertisements displaying aggression and violence in public transit spaces represent a public health concern. The high visibility of ads likely contributes to increased levels of aggression among New York City (NYC) youths traveling across boroughs. Given the importance of the physical, psychological and social environment in shaping the lives of youth, additional attention is warranted regarding how media advertisements are promoted within public transit spaces across America. The aim of this study was to document quantity and placement of advertisements illustrating aggressive and violent content throughout the NYC public transit subway system. Methods: This cross-sectional study was conducted over a five-day period in June 2017. Direct observation was used to document all advertisements within every NYC Metropolitan Transit Authority (MTA) subway station (N = 472) in four NYC boroughs: Bronx, Brooklyn, Manhattan and Queens. Static media advertisements with/without aggressive and violent content displayed on subway platform wall panels above and underground were counted, photographed and described with a mobile app. Results: Aggressive and violent ads in the MTA were pervasive. Subway platforms displayed advertising consisting of guns, individuals fighting and attacking, and words with aggressive language. Conclusion: Public transit spaces provide unregulated visual and verbal messages without citizen participation. Subway stations in NYC and across the country prohibition stance could be a model for violent content reduction. Given the pervasive and tragic effects of aggression and violence on youth and adults, transit agencies could inundate passengers with positive advertising content. Dialogue between citizens and transit agencies to remove noxious messages from public transit spaces warrants the same discussion given to banning alcohol advertisements

Leadership and decision-making practices in public versus private universities in Pakistan

The goal of this study is to examine differences in leadership and decision-making practices in public and private universities in Pakistan, with a focus on transformational leadership (TL) and participative decision-making (PDM). We conducted semi-structured interviews with 46 deans and heads of department from two public and two private universities in Pakistan. Our findings indicate that leadership and decision-making practices are different in public and private universities. While differences were observed in all six types of TL-behaviour, the following three approaches emerged to be crucial in both public and private universities: (1) articulating a vision, (2) fostering the acceptance of group goals, and (3) high-performance expectations. In terms of PDM, deans and heads of department in public and private universities adopt a collaborative approach. However, on a practical level this approach is limited to teacher- and student-related matters. Overall, our findings suggest that the leadership and decision-making practices in Pakistani public and private universities are transformational and participative in nature
