Doing Death in Texas: Language and Jury Decision-Making in Texas Death Penalty Trials
Author: Robin Helene Conley

This thesis examines a means by that denunciation and enlightenment make death-penalty decisions probable by analyzing
jury decision-making in Texas death-penalty trials. The investigate focuses on how specific denunciation choices intercede and restrict
jurors’, attorneys’ and judges’ actions and use when enchanting in and reflecting on collateral trials. The dissertation
shows that when intent in an sincerely aroused state use (i.e., murdering convicted individuals), jurors, attorneys and
judges deceive and confront their impasse in a attack fundamental in this practice. When citing a act of execution, jurors
mostly change a preference to kill a convicted chairman onto a state or repudiate that tellurian beings have intent in an enterprise
set adult to kill another human. Another resource for jurors to equivocate a stress compared to murdering a associate tellurian being is
to welcome a linguistic dehumanization of defendants. Jurors effectively conceal consolation and a fulfilment that a defendant
is, in many respects, like themselves, nonetheless with a opposite credentials and set of use and behaviors. Any worth
a suspect competence have as a associate tellurian being is private by linguistic repetitions that remonstrate jurors a suspect has
finished things that invalidate him or her from being treated as a associate tellurian being. The thesis argues that denunciation is
one of a primary resources by that jurors support defendants as nonhuman, and so confirm to judgment them to death. The
investigate concerned 12 months of fieldwork in and around Houston, Texas. It enclosed interviews of jurors, attorneys, judges
and jail staff; member regard in genocide chastisement trials; audio recordings and note holding of these trials; and qualitative
linguistic analyses of transcribed interviews and courtroom interaction.

NIJ’s Multisite Adult Drug Court Evaluation

This five-year longitudinal process, impact and cost investigate of adult diagnosis drug justice programs sampled scarcely 1,800
drug justice and non-drug-court probationers from 29 rural, suburban and civic jurisdictions opposite a United States. The sample
includes 23 drug courts and 6 comparison groups in 8 states. The expectancy is that module appearance will result
in long-term benefits, that embody declines in drug use and rapist behavior.

The MADCE investigate addresses several investigate questions:

  • What is a impact of adult drug courts on ethanol and other drug use, rapist recidivism, practice and other outcomes?
  • What community, module and delinquent characteristics envision these short- and long-term outcomes?
  • How do changes in short-term outcomes — such as delinquent views and attitudes — mediate a impact of programs on long-term
    outcomes?
  • Are there cost assets attributable to drug justice programs?

Final Technical Report: Neighborhoods, Recidivism, and Employment Among Returning Prisoners
Authors: Jeffrey D. Morenoff and David J. Harding

This investigate examined a change of village context on a labor-market outcomes and recidivism of former prisoners paroled
in Michigan in 2003. The investigate found area facilities were clever predictors of recidivism and labor-market outcomes.
No singular cause creates a area a “risky” sourroundings for parolees. Neighborhood socioeconomic combination was a strong
predictor of labor-market outcomes since parolees who lived in disadvantaged neighborhoods had problem removing employment
and evading poverty. The many strong protecting cause for recidivism was vital in a residentially quick neighborhood;
a many strong risk cause for recidivism was vital in neighborhoods with aloft densities of immature people. Carefully evaluating
a parolee’s area when commendatory new housing sites competence urge outcomes. Other measures could embody fixation institutional
housing for former prisoners in some-more advantaged neighborhoods, and inclusion of area context in risk comment to
urge targeting services to former prisoners vital in high-risk neighborhoods.

Authors: Edna Erez, Gabriel Weimann, and A. Aaron Weisburd

This investigate presents quantitative and qualitative assessments of a calm of communications in a forum discussions on
Jihadist websites that are of many regard to U.S. counterterrorism efforts. The study’s commentary uncover that many Jihadist
online forum discussions are brief, engage few participants from a purebred forum members, and embody few entries and
pages. Forum participants mostly impute viewers to an authorized website and share genuine Jihadist multimedia. References and
quotes from eremite sources are common. Just over one-third of a discussions embody calls for Jihad, and 3 percent
of a communications plead nonterrorist bootleg activities, generally computer-related and software-related offenses.
The forum discussions embody 4 categories of content: information dissemination, eremite preaching, instruction or training,
and amicable interactions. These calm categories support 3 core activities of a militant organization: ideological
foundation, organizational structure, and operational means.

A Model of Static and Dynamic Sex Offender Risk Assessment
Authors: Robert J. McGrath, Michael P. Lasher, and Georgia F. Cumming

This investigate tested models that total immobile and energetic risk measures that competence envision passionate recidivism for adult male
sex offenders softened than any one magnitude alone. The investigate found that a logistic retrogression indication that total measures from
both energetic and immobile risk instruments consistently likely recidivism and outperformed possibly instrument alone when both
instruments had matching predictive power. Static risk factors are unchangeable aspects of a person’s history, since dynamic
risk factors are potentially changeable. Risk-needs instruments assistance diagnosis providers in determining a aspects of an offender’s
behavior, attitudes and needs (dynamic factors) that are receptive to change that leads to a diminution or rejecting of
reoffending. This investigate arguable that assessing energetic risk factors frequently competence assistance providers adjust a intensity
and generation of interventions. The investigate enclosed a representation of 759 adult masculine sex offenders enrolled in village treatment
in Vermont between 2001 and 2007. These offenders were assessed once regulating immobile measures (Static-99R, Static-2002R and VASOR)
formed on their history. A 22-item energetic risk measures comment (Sex Offender Treatment Needs and Progress Scale) was used
mixed times to cruise participants shortly after their entrance into village diagnosis and about any 6 months after that.
Analyses of a energetic comment scores resulted in building a new energetic risk measure, a Sex Offender Treatment Intervention
and Progress Scale (SOTIPS), that was used during 1-year and 3-year follow-up periods.

Authors: Mechthild Prinz, Yingying Tang, Donald Siegel, Heyi Yang, Bo Zhou, and Haiteng Deng

The design of this plan was to establish either a single, assenting methodology, regulating mass spectrometry could be
grown for identifying 5 forensically critical physique fluids. The fluids are blood, saliva, semen, menstrual blood and
vaginal fluid. Researchers identified mixed protein markers for any physique fluid. The formula of these efforts uncover the
value of mass spectrometry as a slight apparatus for physique liquid identification. Multiple markers were identified for blood, saliva
and semen. Detection levels for these 3 physique fluids were in a nanoliter range, that is reduce than other methods currently
used. Body liquid mixtures could be distinguished, and aging for adult to 20 months did not significantly impact representation detection.
In addition, rough formula uncover that all 3 physique fluids are fair to high throughput testing. These commentary show
that mass spectrometry can be used as a singular assenting body-fluid exam that could reinstate a stream exam methods.
This would facilitate standardization for physique liquid contrast opposite laboratories.

Authors: Bruce Taylor, Nan D. Stein, Dan Woods, and Elizabeth Mumford

This examination assessed a efficacy of targeting a immature assembly with classroom-based curriculums and school-level
interventions. The authors incidentally reserved school-based interventions to 30 open center schools in New York City and identified
117 sixth and seventh class classes during pointless to accept total classroom interventions. The classroom involvement was a six-session
curriculum that stressed a effects of dating attack and harassment, laws and penalties, gender roles and healthy relationships.
The building-based involvement enclosed a use of proxy school-based confining orders. It also featured aloft levels
of expertise and confidence participation in areas identified by tyro mapping of vulnerable “hot spots,” and a use of posters
to boost recognition and stating to propagandize personnel. Quantitative surveys were finished during baseline, immediately after
a intervention, and 6 months post-intervention. They enclosed measures of knowledge, attitudes, behavioral aims, willingness
to meddle as a bystander, counterpart and dating partner earthy and passionate violence, passionate nuisance and other background
items. Qualitative concentration groups were conducted with interventionists and students to yield context to cruise intervention
doing and tyro change compared with a interventions. The total classroom and building interventions, and
a “building only” intervention, led to 32-47 percent reduce counterpart passionate attack victimization and perpetration adult to six
