A stadium of hope: A rhetorical analysis of the Promise Keepers

The historical ebb and flow of the Men\u27s Christian Movement has been one of interest and concern to the American public. This concern surfaced once again with the popularity of the Promise Keepers organization. This paper focuses on the rhetorical discourse and strategies of the Promise Keepers organization from a social movement perspective. This study examines the evolutionary states through which social movements evolve; look at specific examples of the discourse to examine the persuasive appeals; and address the leadership tactics and character of Bill McCartney, founder of the Promise Keepers

Listening to Unheard Voices: Nurses’ Communication Experiences with the NRS Pain Scale

This study examines nurses’ experiences with the Numeric Rating Scale (NRS). These responses characterize the communication trials that nurses face with pain diagnosis, pain management, and overall patient care. Interviews with 20 nurses reveal three themes: subject dissatisfaction, feeling limited, and subjective satisfaction. An analysis of these themes reveals the need for renewed discussion about the way pain is communicated and the challenging expectations nurses must regularly confront. Implications for listening to important, but often quiet, even silent, voices in pain management and clinical practice are discussed

Bias in the Evaluation Process: Influences of Speaker Order, Speaker Quality, and Gender on Rater Error in the Performance Based Course

This study examines how variations in speaker order increase the potential for rater error in the performance based course. Seventy-six undergraduate raters were randomly assigned to one of eight treatment groups and asked to grade eight-week training course. Speaker order and presentation quality varied across groups and an ANOVA was used to examine significant differences across rater assessments, feedback quality and rater gender. Significant main effects were identified in each of the eight treatment groups suggesting that speaker order influenced rater scoring

Stretching the Academic Dollar: The Appropriateness of Utilizing Instructor Assistants in the Basic Course

As more universities across the country are feeling the pressures of providing an increasingly rigid financial accountability to tax payers and state legislatures, speech and communication departments find themselves in a precarious position. Namely, how can communication departments teach the budding number of students enrolled in their courses with little increase in budget, while continuing to produce effective speakers? One common answer to this dilemma involves the use of graduate students, and in some cases undergraduate students, as teaching assistants in the basic course. This study examines the efficacy of using undergraduate instructor assistants in the basic course at a large Midwestern University and addresses potential stumbling blocks in training, such as speaker order and rater error. Thirty-eight undergraduate instructor assistants were randomly assigned to one of four treatment groups and asked to grade four 10-minute persuasive speeches following their eight-week training course. An ANCOVA was used to examine significant differences across presentation grades for speakers in each group, while an ANOVA was used to determine differences in the quality of comments based on speaker order. No significant differences were identified in either analysis suggesting that when properly trained, undergraduate instructor assistants can grade consistently across multiple groups regardless of speaker order

Empirical Desert, Individual Prevention, and Limiting Retributivism: A Reply

A number of articles and empirical studies over the past decade, most by Paul Robinson and co-authors, have suggested a relationship between the extent of the criminal law\u27s reputation for being just in its distribution of criminal liability and punishment in the eyes of the community – its moral credibility – and its ability to gain that community\u27s deference and compliance through a variety of mechanisms that enhance its crime-control effectiveness. This has led to proposals to have criminal liability and punishment rules reflect lay intuitions of justice – empirical desert – as a means of enhancing the system\u27s moral credibility. In a recent article, Christopher Slobogin and Lauren Brinkley-Rubinstein (SBR) report seven sets of studies that they argue undermine these claims of empirical desert and moral credibility and instead support SBR\u27s proposed distributive principle of individual prevention, a view that focuses on an offender\u27s future dangerousness rather than on his perceived desert. The idea that there is a relationship between the criminal law\u27s reputation for justness and its crime-control effectiveness did not originate with Robinson and his co-authors. Rather, it has been a common theme among a wide range of punishment theory scholars for many decades. A particularly important conclusion of recent Robinson studies, however, is their confirmation that this relationship is a continuous one: even small nudges in moral credibility can produce corresponding changes in the community\u27s deference to the criminal law. This is important because it shows that even piecemeal changes or changes at the margin – as in reforming even one unjust doctrine or procedure – can have real implications for crime-control. SBR\u27s studies, rather than contradicting the crime-control power of empirical desert, in fact confirm it. Further, SBR\u27s studies do not provide support for their proposed individual prevention distributive principle, contrary to what they claim. While SBR try to associate their principle with the popular limiting retributivism adopted by the American Law Institute in its 2007 amendment of the Model Penal Code, in fact it is, in many respects, just the reverse of that principle. With limiting retributivism, the Model Code\u27s new provision sets desert as dominant, never allowing punishment to conflict with it. SBR would have punishment essentially always set according to future dangerousness; it is to be constrained by desert only when the extent of the resulting injustices or failures of justice is so egregious as to significantly delegitimize the government and its law. This ignores the fact that even minor departures from justice may have an important cumulative effect on the system as a whole. What SBR propose – essentially substituting preventive detention for criminal justice – promotes the worst of the failed policies of the 1960s, where detention decisions were made at the back-end by experts, and conflicts with the trend of the past several decades of encouraging more community involvement in criminal punishment, not less

Structural and magnetic characterization of the complete delafossite solid solution (CuAlO2){1-x}(CuCrO2){x}

We have prepared the complete delafossite solid solution series between diamagnetic CuAlO2 and the t2g^3 frustrated antiferromagnet CuCrO2. The evolution with composition x in CuAl(1-x)Cr(x)O2 of the crystal structure and magnetic properties has been studied and is reported here. The room-temperature unit cell parameters follow the Vegard law and increase with x as expected. The effective moment is equal to the Cr^3+ spin-only S = 3/2 value throughout the entire solid solution. Theta is negative, indicating that the dominant interactions are antiferromagnetic, and its magnitude increases with Cr substitution. For dilute Cr compositions, J_BB was estimated by mean-field theory to be 2.0 meV. Despite the sizable Theta, long-range antiferromagnetic order does not develop until very large x, and is preceeded by glassy behavior. Data presented here, and that on dilute Al-substitution from Okuda et al., suggest that the reduction in magnetic frustration due to the presence of non-magnetic Al does not have as dominant an effect on magnetism as chemical disorder and dilution of the magnetic exchange. For all samples, the 5 K isothermal magnetization does not saturate in fields up to 5 T and minimal hysteresis is observed. The presence of antiferromagnetic interactions is clearly evident in the sub-Brillouin behavior with a reduced magnetization per Cr atom. An inspection of the scaled Curie plot reveals that significant short-range antiferromagnetic interactions occur in CuCrO2 above its Neel temperature, consistent with its magnetic frustration. Uncompensated short-range interactions are present in the Al-substituted samples and are likely a result of chemical disorder

Extracellular DNA Promotes Efficient Extracellular Electron Transfer by Pyocyanin in Pseudomonas aeruginosa Biofilms

Redox cycling of extracellular electron shuttles can enable the metabolic activity of subpopulations within multicellular bacterial biofilms that lack direct access to electron acceptors or donors. How these shuttles catalyze extracellular electron transfer (EET) within biofilms without being lost to the environment has been a long-standing question. Here, we show that phenazines mediate efficient EET through interactions with extracellular DNA (eDNA) in Pseudomonas aeruginosa biofilms. Retention of pyocyanin (PYO) and phenazine carboxamide in the biofilm matrix is facilitated by eDNA binding. In vitro, different phenazines can exchange electrons in the presence or absence of DNA and can participate directly in redox reactions through DNA. In vivo, biofilm eDNA can also support rapid electron transfer between redox active intercalators. Together, these results establish that PYO:eDNA interactions support an efficient redox cycle with rapid EET that is faster than the rate of PYO loss from the biofilm

Selection and gene flow shape genomic islands that control floral guides

Genomes of closely-related species or populations often display localized regions of enhanced relative sequence divergence, termed genomic islands. It has been proposed that these islands arise through selective sweeps and/or barriers to gene flow. Here, we genetically dissect a genomic island that controls flower color pattern differences between two subspecies of Antirrhinum majus, A.m.striatum and A.m.pseudomajus, and relate it to clinal variation across a natural hybrid zone. We show that selective sweeps likely raised relative divergence at two tightly-linked MYB-like transcription factors, leading to distinct flower patterns in the two subspecies. The two patterns provide alternate floral guides and create a strong barrier to gene flow where populations come into contact. This barrier affects the selected flower color genes and tightlylinked loci, but does not extend outside of this domain, allowing gene flow to lower relative divergence for the rest of the chromosome. Thus, both selective sweeps and barriers to gene flow play a role in shaping genomic islands: sweeps cause elevation in relative divergence, while heterogeneous gene flow flattens the surrounding "sea," making the island of divergence stand out. By showing how selective sweeps establish alternative adaptive phenotypes that lead to barriers to gene flow, our study sheds light on possible mechanisms leading to reproductive isolation and speciation

Representations of the family in postwar British amateur film: family histories in the Lane and Scrutton collection at the East Anglian Film Archive

This article examines the construction of the postwar British family in amateur film with reference to the Sidney Lane and Cecil Scrutton collection held at the East Anglian Film Archive (EAFA), particularly the films covering 1948 – 1961. Heather Norris Nicholson argues that home movies contribute to 'an understanding of leisure and visual-related practices of consumption as well as the social processes by which people came to give themselves, and others, identities' in the mid-twentieth century (Nicholson, 2004, p. 323). By considering the social and historical contexts in which these home movies were produced, and using accompanying notes by one of the filmmaker’s sons, the leisure time films of Lane and Scrutton can be analysed in order to understand how the amateur cine hobby ideologically constructed family, community and national identity in postwar Britain. The images of Christmas parties, daytrips and holidays in these films reveal much about this particular family, and are therefore very illuminating to the social historian and film scholar of today
