MENTOR: The National Mentoring Partnership, Herrera, Carla, and Garringer, Michael
- Abstract
One of the realities of being in a mentoring relationship is that, like all human relationships, it will have its ups and downs, moments of joy and moments of challenge. Mentors are not simply friends to young people, nor are they simply "authority figures." They show up to these relationships with purpose and a desire to help that young person explore possibilities, have conversations of learning and healing, set a course for their future, and overcome any challenges that pop up along the way. Because this is a complex role to play, there are skills and approaches mentors may need to bring to a mentoring relationship to enable that young person to get what they need from the experience. This resource will teach the reader about several key aspects of being a mentor: (1) the mindsets and attitudes that lay the foundation for a strong mentoring relationship; (2) basic information about youth development and the typical relationship cycle that might be experienced while mentoring; and (3) critical skills and competencies needed to grow and refine to meet the needs of the young people. All of these are explained in detail in this report. This information will help to fill a mentoring "toolbox" with the skills and attitudes that can help a young person (often referred to as a "mentee" in these types of relationships) on their journey. Because every mentoring relationship is unique, it is likely all of these skills won't apply to every relationship. But the topics highlighted in this resource are the ones that research suggests are extremely valuable in a wide variety of mentoring contexts.

5. The Impact of an Intensive Year-Round Middle School Program on College Attendance

- Abstract
Too many talented students who go to under-resourced schools do not achieve their full potential. Though they may perform very well relative to their classmates, these students do not receive the same kinds of academically challenging opportunities throughout their educational journey as do their counterparts in better-resourced public and private schools. Rather than matriculating to competitive high schools and from there to selective colleges they are qualified to attend, these students often go to less academically competitive high schools and on to colleges where graduation rates are low. Some even forgo college altogether. To address this problem, Higher Achievement offers an intensive, academically oriented program for middle school students in under-resourced schools. Starting in the summer before fifth or sixth grade, Higher Achievement offers its participants, called "scholars," 650 extra hours of academic enrichment and instruction after school and during the summers through the eighth grade. The program includes English and math instruction as well as field trips to competitive high schools and colleges, achievement test preparation, and assistance in applying for financial aid. This short report presents the results of a randomized controlled trial of Higher Achievement that started in 2005, comparing the outcomes of students who were offered the opportunity to participate in Higher Achievement (the program group) and students who were not (the control group). It presents the impacts of the program one, two, and four years after enrollment, as well as its long-term impacts on college attendance. The study found that Higher Achievement was successful at changing the educational trajectory of students through middle school and improved the academic quality of many students' high school experiences, but did not affect the colleges to which they matriculated. By Year 2, there were positive impacts on students' math and reading test scores. In Year 4, the impacts on math test scores remained statistically significant. Higher Achievement had a small impact on the types of high schools its scholars ultimately attended. Program group students were more likely than control group students to matriculate to private or parochial schools and less likely to go to nonacademically competitive charter or magnet schools. By 2019, there was no difference in college going. More than 70 percent of both program and control group students had ever attended college. There were no differences in the academic quality of the colleges Higher Achievement's scholars ultimately attended, as measured by being a two- or four-year college; a college having a lower acceptance rate; or a college whose freshmen on average had higher SAT math or reading scores. Higher Achievement's college impacts did not differ by whether a student's parent had attended college or by student characteristics. The study shows that Higher Achievement is a very effective middle school program, improving students' middle school trajectories. However, the impacts did not persist after the program through high school and college.

- Abstract
Many talented students in under-resourced schools do not reach their full potential. Research shows that by sixth grade, children born into poverty have likely spent 6,000 fewer hours learning than their middle-class counterparts. Higher Achievement, an intensive summer and after-school program, aims to close that learning gap. It offers participants more than 500 hours of academic enrichment activities a year to help them meet the high academic standards expected of college-bound students. Known as "scholars," Higher Achievement students enter the program during the summer before either fifth or sixth grade and commit to attending through eighth grade. The summer program consists of six weeks of morning classes in English Language Arts (ELA), math, science, and, in some centers, social studies, followed by enrichment activities in the afternoon, including chess, cooking, art, and soccer. During the school year, in addition to the program's regular study hall and enrichment activities, a cadre of mostly young professionals volunteer one day a week, delivering 75-minute ELA or math lessons to small groups of scholars. These volunteers receive detailed lesson plans and training so they can successfully execute the program's rigorous curricula. Part of what makes Higher Achievement affordable is its use of volunteers in this way. An earlier experimental evaluation of Metro DC, Higher Achievement's flagship affiliate in Washington, DC, and Alexandria, Virginia, found that the program was effective in improving academic performance two years after students applied. Since then, Higher Achievement has expanded to three new cities: Baltimore, Maryland; Richmond, Virginia; and Pittsburgh, Pennsylvania. Keenly aware that many effective flagship programs fail to be effective in new locations, the federal government funded an experimental validation study to examine the impacts at these expansion sites. Eligible students were randomly assigned either to a program group that could participate in Higher Achievement, or to a control group that could not enroll in the program. Comparing the two groups' outcomes provided an estimate of the program's impacts. The study found that the expansion sites experienced many of the implementation challenges common to school-based, out-of-school-time programs (for example, staff turnover, coordination with the host school, and lower-than-hoped-for attendance by middle school students), as well as those often seen in new programs (such as a lack of strong relationships with key partners and difficulty recruiting volunteers). Even so, Higher Achievement was found to be at least adequately implemented in all three cities. The study found that the program's detailed lesson plans, with scripted questions and student instructions, enabled the volunteers to deliver rigorous academic lessons. This report addresses the following questions: (1) How did the Higher Achievement centers operate during the study and what lessons are there for similar programs?; (2) Did scholars receive more academic enrichment over the two-year study period than they would have received without Higher Achievement?; and (3) How did Higher Achievement impact scholars' grades and test scores over the two years since they applied?

Poon, Cyanea Y. S., Herrera, Carla, Jarjoura, Roger, McQuillin, Samuel D., Keller, Thomas E., and Rhodes, Jean E.
- Abstract
Youth referred to mentoring programs vary considerably in the range and severity of difficulties (i.e., behavioral, internalizing, social and academic) and environmental challenges they face. However, their patterns of risk and corresponding consequences for mentoring have rarely been investigated. This study draws on data for youth participants in 30 mentoring programs (n = 2,165, 55.1% females) to examine patterns of presenting challenges. Four profiles emerged using three-step latent profile analyses. Profiles with more intensive symptoms were associated with more environmental stressors. Moreover, there were significant differences between profiles in youth-perceived relationship attributes, including closeness, youth-centeredness, growth focus and mentor-mentee relational health. The profile with the highest externalizing and social challenge indicators scored the lowest across these four relational indices. The results highlight variability of youth risk at baseline, and its differential impact on mentoring relationship outcomes. Implications for mentoring programs are discussed.

11. VO Supported on Functionalized CNTs for Oxidative Conversion of Furfural to Maleic Anhydride.

Rodríguez, Pedro, Parra, Carolina, Díaz de León, J. Noe, Karelovic, Alejandro, Riffo, Sebastian, Herrera, Carla, Pecchi, Gina, and Sepúlveda, Catherine
- Abstract
Commercial non-functionalized (CNTs) and functionalized carbon nanotubes (CNT-COOH and CNT-NH
2 ) were used as supports to synthesize vanadium-supported catalysts to be used in the gas phase partial oxidation of furfural towards maleic anhydride (MA). The CNTs and the VO2 -V2 O5 /CNTs, so-called VO/CNT catalysts, were characterized by AAS, TGA, XRD, N2 adsorption isotherms at −196 °C, Raman, NH3 -TPD and XPS. The surface area values, TGA and XRD results indicate that the larger thermal stability and larger dispersion of vanadium species is reached for the VO/CNT-NH2 catalyst. XPS indicates presence of surface VO2 and V2 O5 species for the non-functionalized (CNT) and functionalized (CNT-COOH and CNT-NH2 ) catalysts, with a large interaction of the functional group with the surface vanadium species only for the VO/CNT-NH2 catalyst. The catalytic activity, evaluated in the range 305 °C to 350 °C, indicates that CO, CO2 and MA yield (%) and MA productivity are associated to the redox properties of the vanadium species, the oxygen exchange ability of the support and the vanadium–support interaction. For the reaction temperatures between 320 °C and 335 °C, the maximum MA yield (%) is found in the functionalized VO/CNT-COOH and VO/CNT-NH2 catalysts. This behavior is attributed to a decreased oxidation capability of the CNT with the functionalization. In addition, VO/CNT-NH2 is the more active and selective catalyst for MA productivity at 305 °C and 320 °C, which is related to the greater interaction of the surface vanadium species with the -NH2 group, which enhances the redox properties and stabilization of the VO2 and V2 O5 surface active sites. Recycling at 350 °C resulted in 100% furfural conversion for all catalysts and a similar MA yield (%) compared to the fresh catalyst, indicating no loss of surface active sites.

Understanding the extent to which youth and families experienced COVID-related stress requires accounting for prior levels of stress and other associated factors. This is especially important for military families, which experience unique stressors and may be reluctant to seek outside help. In this prospective study, we examined the role of pre-pandemic family factors in predicting parent and youth stress during the COVID-19 pandemic. Participants were 234 families with at least one active-duty parent and a 3
rd or 5th -grade child. Findings revealed that preexisting factors predicted youth and family COVID-related stress. Specifically, heightened pre-pandemic parental stress and youth internalizing symptoms were significant predictors of COVID-related stress. Implications for mental health professionals and other organizations supporting military parents and families during the COVID-19 pandemic as well as other times of upheaval are discussed.

Kanchewa, Stella S., Yoviene, Laura A., Schwartz, Sarah E. O., Herrera, Carla, and Rhodes, Jean E.
- Abstract
In this study, we examined associations between mentoring relationship quality, rejection sensitivity, and youth outcomes. Participants (N = 446) were part of a national, random assignment evaluation of Big Brothers Big Sisters of America school-based mentoring programs. Youth in more trusting mentoring relationships demonstrated reductions in teacher-reported behavioral evidence of rejection sensitivity. These reductions, in turn, were positively associated with youth's assertiveness with peers and prosocial behavior. Percentile bootstrap confidence intervals testing indirect effects demonstrated that rejection sensitivity mediated the association between mentoring relationship trust and teacher-reported assertiveness and prosocial behavior. Implications of the findings for theory and practice are discussed.

A series of pure and 50 % substituted Fe‐containing (LaFeO3, LaFe0.5Ni0.5O3 and LaFe0.5Co0.5O3) and Co/Ni‐containing (LaCoO3, LaNiO3, and LaCo0.5Ni0.5O3) perovskites were used as precursors to synthesize metallic reduced catalysts to be tested for the liquid hydrogenation of furfural. The catalytic reaction was carried out in a batch reactor at 200 °C and 3.0 MPa of H2 pressure. The calcined perovskites and reduced catalysts were characterized by X‐ray diffraction (XRD), N2 physisorption at 77 K, temperature programmed reduction (H2‐TPR), temperature programmed CO2 and NH3 desorption (CO2‐TPD and NH3‐TPD), Atomic Absorption Spectroscopy (AAS) and X‐ray photoelectron spectroscopy (XPS) techniques. The LaCo0.5Ni0.5O3 reduced catalyst display the highest activity in furfural conversion, which was attributed to a cooperative effect between highly dispersed nickel and cobalt metal nanoparticles after reduction process. The effect of the nature of B‐cation have a high impact on the products selectivity in the hydrogenation of furfural, suggesting that enriched‐Ni metal surface was selectivity to tetrahydrofurfuryl alcohol, meanwhile enriched‐Co metal surface was selective to furfuryl alcohol formation, which was also supported with adsorption mode of furfural over the active sites obtained by quantum calculation.

- Abstract
"The Role of Risk: Mentoring Experiences and Outcomes for Youth with Varying Risk Profiles" presents findings from the first large-scale study to examine how the levels and types of risk youth face may influence their relationships with program-assigned mentors and the benefits they derive from these relationships. The study looked closely at the backgrounds of participating youth and their mentors, the mentoring relationships that formed, the program supports that were offered, and the benefits that youth accrued--and assessed how these varied for youth with differing "profiles" of risk. Five key findings resulted: (1) Without substantial effort beyond their normal outreach strategies, programs were able to reach and serve youth facing a wide range of challenges; (2) Youth with differing risk "profiles" (that is, levels and types of risk) had relationships of similar strength and duration and derived similar benefits from program participation; (3) The challenges reported by mentors and the reasons matches ended differed as a function of youth's risk profile; (4) The strongest program benefit, and most consistent across risk groups, was a reduction in depressive symptoms--a particularly noteworthy finding given that almost one in four youth reported worrisome levels of these symptoms at baseline. Findings also suggested gains in social acceptance, academic attitudes and grades. Youth did not appear to benefit in their relationships with parents or in their positive or negative behaviors; and (5) Mentors who received early-match training and consistent program support met more frequently and had longer-lasting relationships with their mentees. Youth whose mentors received training also reported higher-quality relationships. The authors believe the study's results provide useful guidance for practitioners, funders, and policymakers who want to know which youth are best suited for mentoring and how practices might be strengthened to help ensure that youth facing a variety of risks get the most out of their mentoring experience. Seven appendixes are included: (1) Study Method; (2) Analysis of Program Outcomes; (3) Who Were the Mentors?; (4) Measuring Risk; (5) Development and Validation of Mentoring Relationship Quality Scales (by Daniel A. Sass and Michael J. Karcher); (6) Analyses of the Effects of Rematching and Total Time Mentored on Youth Outcomes (by David L. DuBois, Daniel A. Sass and Michael J.

20. Staying on Track: Testing Higher Achievement's Long-Term Impact on Academic Outcomes and High School Choice
- Author

MDRC, Herrera, Carla, Grossman, Jean Baldwin, and Linden, Leigh L.
- Abstract
One crucial decision that middle schoolers (and their families) make is where they will attend high school. Many districts employ school choice systems designed to allow students to pick a high school that will meet their needs and interests. Yet most students prefer high schools that are close to home, and for youth in low-income neighborhoods, this often means attending a more disadvantaged, lower performing school (Nathanson et al. 2013). Youth who defy these odds and choose a competitive high school instead have much to gain. Cullen et al. (2005), for instance, found that Chicago public middle school students who chose to attend a higher-achieving high school were substantially more likely to graduate. However, even as eighth graders, these students already differed in many ways from their peers who chose a neighborhood school--they had better self-reported grades and higher expectations for the future, felt more prepared for high school, and were more likely to have spoken with their parents about what school to attend. These findings raise the question of how we can prepare more disadvantaged students to take the many steps necessary-throughout the middle school years-to successfully transition to a competitive, high-quality high school that can ultimately launch them toward college and careers. The Washington, DC-based Higher Achievement program is taking on this challenge. Higher Achievement targets rising fifth and sixth graders from "at-risk communities" and serves them throughout the middle school years. Its goal is to strengthen participants' academic skills, attitudes and behaviors, reinforce high aspirations and help students and their families navigate the process of applying to and selecting a high-quality high school. In 2006, the authors began a comprehensive multi-year evaluation of Higher Achievement to test its impact on participants' academic performance, attitudes and behaviors and on their high school enrollment. The evaluation used random assignment-the most rigorous design available to researchers-to assess program impacts. This brief summarizes the study's findings. Findings suggest that the program does appear to expand the options available to its students by making them more likely to apply to and attend private schools and less likely to apply to and attend weaker public magnet and charter schools. This, in turn, may position youth for better outcomes in high school and beyond.

MENTOR/National Mentoring Partnership, Karcher, Michael, and Herrera, Carla
- Abstract
School-based mentoring (SBM) is an adaptation of the traditional mentoring model for schools. Involving schools can help programs reach groups of youth who may not otherwise be served, but school-based programs and their matches must adjust to the structure of the school. Available research suggests new and additional mentor training, staff support, and match maintenance efforts, such as summer contacts, may be necessary if SBM is to maximize its potential. There also is some evidence that the school poses unique constraints on mentoring that may interact with developmental and gender norms to make it more effective for some youth than others. Adapting school-based mentoring in ways that better suit the specific needs of boys and girls of different ages will be a significant next step in the realization of potential benefits of this approach to promoting positive youth development. The article is followed by suggestions on how practitioners can incorporate the research findings into mentoring programs and a list of additional resources. [The 10-issue "Research in Action" series, edited by Jean E. Rhodes, is the initial project of the MENTOR Research and Policy Council, charged with taking current mentoring research and translating it into useful, user-friendly materials for mentoring practitioners.

Public/Private Ventures, Philadelphia, PA., Herrera, Carla, and Arbreton, Amy J. A.
- Abstract
Boys & Girls Clubs in New York City and Boston participated in a 3-year initiative to provide and enhance services to underserved teens. Researchers collected data via surveys of club members and staff; cost surveys of club administrators; interviews, focus groups, and observations at each club; and attendance information. Results indicated that these voluntary youth-serving organizations drew in many community teens. In 1 year, Boston added from 20-100 new teen members at each club, while New York added from 201-1,100 new teens. Clubs that went beyond recruitment goals experienced difficulty meeting teens' needs. Clubs reached teens with such strategies as increased hours of activities, collaborations with outside agencies, and targeted street outreach. Programs served teens with many needs, though they found this challenging. Sustaining teens' involvement was more difficult than recruitment. Clubs retained a little over half of their target groups for at least a full year. About 40 percent of teens attended less than once a month. Program challenges included hiring appropriate staff, preventing turnover, and providing sufficient staff training. Clubs were quite successful in providing teens with emotional and instrumental support. Over three-quarters of teens reported feeling safe at their clubs. Clubs in both cities invested in improvements in their management information systems. Appendices include youth survey scales and constructs and characteristics of youth survey participants.

Public/Private Ventures, Philadelphia, PA., Herrera, Carla, Vang, Zoua, and Gale, Lisa Y.
- Abstract
This study investigated three innovative group mentoring programs and examined findings from data collected in two earlier studies of mentoring programs. The three programs were YouthFriends, which provided technical assistance to school districts establishing school-based mentoring programs; TEAMWORKS, which organized teams of mentors to meet with groups of middle school students; and the Group Mentoring Program of the Be-A-Friend Big Brothers and Big Sisters Program, which assigned paid staff to mentor small groups of youth. Researchers interviewed program and school staff, youth, and mentors, and held focus groups with 12 additional mentors. The previous study involved interviewing mentors working with groups of youth and working one-on-one. Results indicate that group mentoring attracts volunteers who are less likely to volunteer for individual mentoring. The onsite programming of many group programs facilitates recruitment of youth who may have been missed by traditional recruitment efforts. Although most group mentors want to develop personal relationships with youth, they place more emphasis on improving peer interactions. While mentor-youth relationships can develop in group settings, the quality of these relationships varies widely. Participants reported improvements in youth's social skills, relationships with nongroup members, and academic performance and attitudes. (Contains 15 tables and 43 references.) (SM)

- Abstract
This study explored the experiences of volunteers and the development of relationships within the two largest contingents of one-on-one mentoring programs: community-based programs and school-based programs. The emphases of school-based programs were studied, along with the quality of developed relationships between youth and mentors and the benchmarks programs can use to ensure optimal development of supportive relationships. A survey was completed by 1,101 mentors in 98 mentoring programs. Mentors in school-based programs were found to spend more time working on academics or doing homework with their mentees. Mentors in school-based programs were of many ages, but mentors in community-based programs were almost all aged 22 to 49. School-based programs delivered fewer contact hours but were also slightly less expensive to conduct. Over 90% of mentors in both types of programs said that they felt close to their mentees, but more community-based mentors felt "very close" to their mentees. Nine factors that provide benchmarks of developing relationships were: (1) engaging in social activities; (2) engaging in academic activities; (3) number of hours per month spent together; (4) decision-making shared by mentor and mentee; (5) prematch training; (6) postmatch training; (7) mentor screening (only important relationship development in community-based programs); (8) matching; and (9) age of the mentee. Results suggest that a school-based approach to providing disadvantaged youth with volunteer mentors is a promising complement to the traditional community-based mentoring model. Practices that facilitate the development of mentor-mentee relationships are reviewed. Appendixes contain a list of members of the Public Policy Council of the National Mentoring Partnership and a discussion of study methodology. (Contains 10 tables and 20 references.) (SLD)

- Abstract
Given the strong interest in school-based mentoring programs, Public/Private Ventures visited two exemplary mentoring programs chosen by the Big Brothers Big Sisters of America (BBBSA). One program was in Green County, Oklahoma, and the other in Jacksonville, Florida. Researchers talked with parents, teachers, children, and mentors to learn more about how the programs operated and the effects they have on the students and the school. The visits led to four conclusions: (1) school-based mentoring programs reach volunteers and youth who would not participate in community-based programs; (2) school staff provide information to BBBSA staff to help create strong matches and supervise these matches closely; (3) mentoring in the school context can provide volunteers with support and enable them to act as educational advocates for youth; and (4) strong relationships can develop within the school context, and these relationships can make a difference in the lives of youth. Study findings suggest that involving youth in well-run school-based mentoring programs can be an effective way to address the needs of disadvantaged youth. (Contains 17 endnotes.) (SLD)

Objective: Interest in promoting more widespread use of evidence-based practice standards in mentoring programs is rising. To describe and better understand efforts to implement recommended standards, we studied a multilevel initiative by a national advocacy organization in which state-level affiliates guided local mentoring programs through a structured quality improvement process. Specifically, we examined organizational readiness for change among mentoring program staff and staff from the state-level affiliates charged with supporting the programs as they implemented their change process. Method: We conducted in-depth qualitative interviews with 44 staff from eight affiliates and 20 programs. Verbatim interview transcripts were coded thematically, with themes organized around perceptions of organizational change commitment and change efficacy. Results: Programs and affiliates were generally highly motivated and committed to the change process. However, when resources needed to make program changes were not available, staff were more measured in their perceptions of change efficacy and noted challenges that weakened the implementation process. Conclusions: Participant experiences illuminate challenges faced by mentoring programs seeking to implement evidence-based practice standards and the state-level affiliates tasked with supporting programs. Support for implementation processes matters greatly for achieving desired outcomes. High commitment to the Quality Mentoring System process was not always accompanied by the strong change efficacy needed. [ABSTRACT FROM AUTHOR]

Most research on youth mentoring relationships has focused on the mentor–mentee dyad, yet caregivers play an important role in supporting these relationships. Drawing on a large, multisite sample of youth in formal mentoring programs (N = 2165), this study investigated associations between caregiver–mentor collaboration and mentoring relationship outcomes in the context of environmental and individual youth risk factors. Analysis of novel quantitative measures assessing caregivers' experiences of the mentoring relationships revealed two factors reflecting caregivers' collaboration with mentors (caregiver involvement and mentor backing), and three factors reflecting caregivers' perceptions of mentor effectiveness (meeting youth needs, advocating for youth, and supporting youth behavior). Results indicated that greater caregiver involvement was associated with higher‐quality and longer‐lasting mentoring relationships. Few associations between risk and mentoring relationships were observed; however, indirect effects indicated that youth environmental risk was positively associated with caregiver involvement, which, in turn, was positively associated with mentoring relationship outcomes.

This study investigates how the implementation of program‐level practices by formal youth mentoring programs is associated with the quality of youth mentoring relationships as contexts for youth development and also examines whether this connection is mediated by the mentor‐staff working alliance. Using data from mentors (n = 542) participating in multiple programs (n = 55), multilevel path models examined hypothesized direct and mediated effects. Parallel analyses were conducted with assessments of program practices from staff (n = 219). Greater exposure to program practices was associated with higher ratings of mentoring relationship satisfaction, commitment, and security and lower mentor‐youth relationship negativity. The mentor‐staff working alliance either partially or fully mediated these associations. Staff‐reported practices predicted mentoring relationship satisfaction and commitment without mediation by the working alliance. This study suggests program practices contribute to stronger youth mentoring relationships. The findings also highlight the mentor‐staff working alliance in supporting the development of positive mentoring relationships. [ABSTRACT FROM AUTHOR]

MENTORING ,STRUCTURAL equation modeling - Abstract
Keller's systemic model of youth mentoring posits there are multiple pathways through which all stakeholders in the youth mentoring process, including the program staff who support the match (or case managers), influence youth outcomes. This study examines case managers' direct and indirect contributions to match outcomes and tests how transitive interactions facilitate a theorized sequence of mentoring interactions to effect greater closeness and length, specifically in nontargeted mentoring programs. A structural equations model of case manager contributions to match outcomes was tested using data from 758 mentor‐mentee matches, supported by 73 case managers across seven mentoring agencies. Results reveal direct effects of mentor‐reported match support quality on match length and indirect influences on match length through increasing youth‐centeredness, goal‐focused orientation, and closeness. The findings confirm the presence of multiple pathways of influence, including indirect effects on outcomes via transitive interactions in match support that scaffold youth‐centeredness and goal‐focused interactions in the match. Findings also suggest supervisors' evaluations of case managers may provide little information about how match support influences the nature of mentor–mentee interactions. [ABSTRACT FROM AUTHOR]

A systematic study on the use of noble metals (Pd, Pt, Au) supported on titanate nanotubes (NT-Ti) for selectively producing BTX and p-cymene from waste tire pyrolysis is provided here. All the materials were characterized for chemical, textural and structural properties using a range of analytical techniques. The M/NT-Ti (M: Pd, Pt, or Au) catalysts exhibit low nanoparticle sizes (1.8 Pt ≈ Au > support > non-catalyst. The Py-GC/MS suggest that the catalysts participate in the secondary reactions of dealkylation, dehydrogenation, isomerization, aromatization, and cyclization leading to a higher formation of BTX than the uncatalyzed reaction. Finally, a comprehensive reaction pathway describing the catalytic pyrolysis of WT over Pd/NT-Ti was proposed by studying the catalytic pyrolysis of individual polymers constituting the waste tires, and D,L-Limonene., Puede accederse a los datos primarios de este trabajo haciendo clic en "Documentos relacionados"., Centro de Investigación y Desarrollo en Ciencias Aplicadas

- Abstract
This study explores the pathways through which school-based mentoring relationships are associated with improvements in elementary and high school students' socio-emotional, academic, and behavioral outcomes. Participants in the study (N = 526) were part of a national evaluation of the Big Brothers Big Sisters school-based mentoring programs, all of whom had been randomly assigned to receive mentoring at their schools over the course of one academic year. Students were assessed at the beginning and end of the school year. The results of structural equation modeling showed that mentoring relationship quality, as measured by the Youth-Centered Relationship scale and the Youth's Emotional Engagement scale, was significantly associated with positive changes in youths' relationships with parents and teachers, as measured by subscales of the Inventory of Parent and Peer Attachment, the Teacher Relationship Quality scale, and the Hemingway Measure of Adolescent Connectedness. Higher quality relationships with parents and teachers, in turn, were significantly associated with better youth outcomes, including self-esteem, academic attitudes, prosocial behaviors, and misconduct. The effect sizes of the associations ranged from 0.12 to 0.52. Mediation analysis found that mentoring relationship quality was indirectly associated with some of the outcomes through its association with improved parent and teacher relationships. Implications of the findings for theory and research are discussed. (Contains 3 tables and 3 figures.)

An MCM-41-SO3H catalyst with 14 wt% S was successfully synthesized to be used in furfural production from xylose and hemicellulose in a biphasic n-butanol/water system. The precursor MCM-41 and the acid-functionalized MCM-41-SO3H catalyst were characterized by XRD, FTIR, TEM, N2 physisorption, ICP-MS, TPD-NH3, and XPS. The characterization results indicated that the sulfonic process partially decreased the ordered mesoporous structure and increased the acid strength of the initial MCM-41. The catalytic performance of the xylose conversion was evaluated in a batch-type reactor using different biphasic ecological and renewable n-butanol/water ratios (1:1, 1.5:1, 2:1, and 2.5:1) as dissolvent at 170 °C. The effect of the dissolvent mixture was clearly seen from the larger initial reaction rate and TOF values for the 1.5:1 ratio. This catalytic behavior indicated that a proper proportion of n-butanol/water dissolvent mixture enhanced the solubility of the substrate in the n-butanol-rich mixture and prevented the deactivation of acidic sulfonated surface groups. To achieve transformation of lignocellulosic raw material to value-added products, the MCM-41-SO3H catalyst was also used for the production of furfural. The recycling evaluation tests indicated that for the recovered catalyst submitted to a sulfonation process, the yield of furfural was closer to the fresh catalyst. [ABSTRACT FROM AUTHOR]

Schwartz, Sarah E. O., Rhodes, Jean E., Chan, Christian S., and Herrera, Carla
- Abstract
Associations between youths' relationship profiles and mentoring outcomes were explored in the context of a national, randomized study of 1,139 youths (54% female) in geographically diverse Big Brothers Big Sisters school-based mentoring programs. The sample included youths in Grades 4-9 from diverse racial and ethnic backgrounds, the majority of whom were receiving free or reduced-price lunch. Latent profile analysis, a person-oriented approach, was used to identify 3 distinct relational profiles. Mentoring was found to have differential effects depending on youths' preintervention approach to relationships. In particular, youths who, at baseline, had satisfactory, but not particularly strong, relationships benefited more from mentoring than did youths with profiles characterized by either strongly positive or negative relationships. Implications for research and practice are discussed. (Contains 1 figure and 8 tables.)

- Abstract
This random assignment impact study of Big Brothers Big Sisters School-Based Mentoring involved 1,139 9- to 16-year-old students in 10 cities nationwide. Youth were randomly assigned to either a treatment group (receiving mentoring) or a control group (receiving no mentoring) and were followed for 1.5 school years. At the end of the first school year, relative to the control group, mentored youth performed better academically, had more positive perceptions of their own academic abilities, and were more likely to report having a "special adult" in their lives. However, they did not show improvements in classroom effort, global self-worth, relationships with parents, teachers or peers, or rates of problem behavior. Academic improvements were also not sustained into the second school year. (Contains 4 tables.)

- Abstract
Out-of-school time (OST) programs represent a vital opportunity and resource for learning and development for children and youth. Given the potential of city-level OST initiatives to support participation, and against the national backdrop of inequitable access to quality OST programs for older youth from disadvantaged communities, The Wallace Foundation commissioned this research study. To understand how to promote sustained participation in OST programs, this study examined the program characteristics--both program practices and structural features--associated with high participation and retention that were employed by OST programs, primarily serving disadvantaged youth, in six cities that have worked toward building OST initiatives. In particular, this report addresses how OST programs keep middle and high school youth engaged over time (i.e., the duration of participation) and how the supports that city initiatives provide can help foster youth participation, with the assumption that programs can have a potentially greater impact if they are able to work with these youth over an extended period of time. Appendices include: (1) Cities and Initiatives; (2) Youth Participation Community of Practice; (3) Respondent List; (4) Sample Selection and Description; (5) Analysis Description; (6) Twenty-Eight Programs/Organizations Interviewed; and (7) Practices and Features of High-Retention Programs.

- Abstract
Whether relational or goal-directed interactions are most useful in youth mentoring has been frequently debated, but until recently, little work had been done to understand how such interactions manifest to create viable relationship styles. The authors' findings in the first study they explore in this article support Karcher and Nakkula's assertion that relational and goal-directed interactions are distinct. The authors found that both made significant contributions to relationship quality, but for children and preadolescents, relational interactions appeared to be more strongly associated with the quality of the mentoring relationship than did goal-oriented interactions. Karcher and Nakkula further suggest that it is when the focus of interactions (relational and goal-directed) emerges through collaborative dialogue that the strongest relationship styles emerge. In their second study, the authors found that cross-age peer mentoring (school-based) matches that selected their activities collaboratively had higher-quality mentoring relationships (mentor and youth reported) than those matches whose activities were typically selected unilaterally by either the program or the mentee alone.

- Abstract
High schools have recently become a popular source of mentors for school-based mentoring (SBM) programs. The high school Bigs program of Big Brothers Big Sisters of America, for example, currently involves close to 50,000 high-school-aged mentors across the country. While the use of these young mentors has several potential advantages, their age raises questions about their capacity to be consistent, positive role models, and, in turn, their potential to yield strong impacts for the youth they mentor. With support from The Atlantic Philanthropies and in collaboration with Big Brothers Big Sisters of America, Public/Private Ventures set out to address these questions using data from our large-scale random assignment impact study of Big Brothers Big Sisters SBM (Herrera, et al. 2007). We found that, on average, high school students were much less effective than adults at yielding impacts for the youth they mentor. However, our research identified several program practices that were linked with longer, stronger and more effective high school mentor relationships. High School Students as Mentors stresses the need for programs with high school volunteers to use the inherent strengths of these volunteers and, at the same time, meet their distinct needs. Big Brothers Big Sisters of America is already initiating most of the changes suggested in the study in its high school Bigs program; it has convened a group of six of its strongest Big Brothers Big Sisters agencies to review these and other findings and share their own experiences and strategies in an effort to strengthen their model.

- Abstract
School-based mentoring is one of the fastest growing forms of mentoring in the US today; yet, few studies have rigorously examined its impacts. This landmark random assignment impact study of Big Brothers Big Sisters School-Based Mentoring is the first national study of this program model. It involves 10 agencies, 71 schools and 1,139 9- to 16-year-old youth randomly assigned to either a treatment group of program participants or a control group of their non-mentored peers. Surveys were administered to all participating youth, their teachers and mentors in the fall of 2004, spring of 2005 and late fall of 2005. The report describes the programs and their participants and answers several key questions, including: Does school-based mentoring work? What kinds of mentoring experiences help to ensure benefits? How much do these programs cost? Our findings highlight both the strengths of this program model and its current limitations and suggest several recommendations for refining this promising model--recommendations that Big Brothers Big Sisters agencies across the country are already working to implement. Eight appendixes are included: (1) Methodology; (2) Impact Analyses; (3) Participating Schools; (4) Associations between Match Support and Training and Indicators of Match Success; (5) Effect Sizes; (6) Does BBBS SMB Provide Different Benefits for Different Groups of Littles?; (7) Follow-Up Analyses to Further Explore Associations between Match Length, Relationship Quality and Outcomes; and (8) Outcome Trajectories for One-School-Year and 15-Month Littles.

- Abstract
Public/Private Ventures (P/PV) recently launched a multiyear study to understand the role that Boys & Girls Clubs play in the lives of early adolescents. Beyond Safe Havens, a prelude to the larger study, reviews the range of evaluations that have been conducted on Boys & Girls Clubs over the past 20 years. The report identifies the potential benefits of the many discrete programs provided by Clubs and discusses three additional studies that examined the broader club experience. It also outlines the strategies that seem to have contributed to the Clubs' successes, as well as any challenges that may have impeded more positive results. The report concludes with a brief description of a planned longitudinal evaluation of Club members as they transition to high school--an evaluation meant to provide documentation of the effect of teens' broad Club experiences on a wide range of outcomes.

Public/Private Ventures, Philadelphia, PA. and Herrera, Carla
- Abstract
With traditional mentoring programs working hard to attract new kinds of volunteers and schools facing increased pressure to help students succeed, school-based mentoring is a promising--and increasingly popular--approach. According to Big Brothers Big Sisters of America, the number of school-based matches grew from 27,000 in 1999 to 90,000 in 2002, an increase of 233 percent. P/PV has published two previous reports on the school-based mentoring model. "School-Based Mentoring: A Closer Look" follows up on those earlier studies by analyzing the results of surveys we conducted with youth, mentors, teachers and case managers involved in three BBBS school-based mentoring programs. The report addresses the following questions: What are the characteristics of mentor-youth matches in school-based programs? What is the quality of the relationships? And what kinds of benefits may youth be gaining from involvement? (Four appendixes are included: (1) Methodology; (2) Survey Scales and Constructs; (3) What Can this Study Tell Us about Self-Assessment and Evaluation?; and (4) Econometric Analysis of the Benefits of School-Based Mentoring (Amanda Bayer). Contains 20 endnotes, 7 figures and 1 table.)
