The European university landscape: A micro characterization based on evidence from the Aquameth project

This paper provides a new and systematic characterization of 488 universities, from 11 European countries: Finland, France, Germany, Hungary, Italy, Netherlands, Norway, Portugal, Spain, Switzerland and UK. Using micro indicators built on the integrated Aquameth database, we characterize the European university landscape according to the following dimensions: history/foundation of university, dynamics of growth, specialization pattern, subject mix, funding composition, offer profile and productivity.     

Szenario-basierter Systemtest von Software-Produktfamilien

Zusammenfassung In der Produktfamilienentwicklung werden durch zwei Entwicklungsprozesse, Domain und Application Engineering, zun"achst wiederverwendbare Entwicklungsartefakte produziert, um diese anschlie?end zur Konstruktion von kundenspezifischen Applikationen einzusetzen. Die Wiederverwendbarkeit wird durch die explizite Definition der Variabilit"at der geplanten Applikationen einer Produktfamilie erzielt. Diese proaktive Wiederverwendung ist bisher in den konstruktiven Entwicklungsphasen realisiert, jedoch noch nicht im Test. Mit ScenTED (Scen_ario based TE_st Case D_erivation) wird in diesem Beitrag eine wiederverwendungsorientierte Technik zur Testfallerstellung f"ur den Systemtest, dem Test eines ausf"uhrbaren Systems gegen spezifizierte Use-Cases, von Produktfamilien vorgestellt. ScenTED basiert auf zwei Kernideen: der Erhaltung der Variabilit"at in Testf"allen und der Szenario-basierten Verfeinerung der Testf"alle. Durch die Erhaltung der Variabilit"at wird die Wiederverwendbarkeit von Testf"allen gesichert; die Szenario-basierte Verfeinerung erm"oglicht Nachvollziehbarkeit durch die durchg"angige Nutzung von Szenarien.

Product family engineering consists of two development processes: Domain engineering and application engineering. Reuseable artefacts are created in the domain engineering process. These artefacts are used for the creation of customer specific applications during the application engineering process. Reusability is achieved with the explicit definition of variability that specifies the potential applications of the product family. The proactive reuse has been realized in the construnction phases of the development process, but not within the test phases. We propose ScenTED (Scen_ario based TE_st Case D_erivation) for the creation of reusable test cases for a use case based system testing in product family engineering. ScenTED has two key ideas: The first is the preservation of variability in test cases and the second idea is the scenario-based refinement of test cases. The preservation of variability ensures the reusability of test cases. The scenario-based refinement enables the traceability from requirements to test cases. We present the ScenTED technique in this article with an example and discuss an industrial case study.

Flavor aversions and deprivation state

In the first four experiments, it was found that aversions to saccharin solution produced by contingent poisoning were similar regardless of whether the rats had been trained under the test deprivation or under a different deprivation; the two deprivation states used were thirst and satiety. In Experiment 5, rats were poisoned after drinking grape juice while hungry or poisoned after drinking milk while thirsty, but they were not poisoned after grape-thirst or milk-hunger combinations. In abstract terms, poisoning occurred after AX and BY stimulus combinations, but did not occur after AY and BX combinations. There was some learning under these discrimination conditions.     

Child sexual abuse prevention: evaluation and one-year follow-up

Because of the high incidence and negative psychological consequences of child sexual abuse, prevention programs have been developed and implemented nationwide. Few programs, however, have been comprehensively evaluated. In this multimodal study, a 3-session adaptation of the Feeling Yes, Feeling No curriculum was provided to 286 third and fourth graders from four schools whose responses were compared to 113 delayed-treatment control children from two schools. Program impact was assessed using a knowledge scale, the State-Trait Anxiety Inventory for Children, a videotape vignettes measure, a parent questionnaire, and disclosure data. Treatment children exhibited significantly greater knowledge and better ability to discriminate safe from unsafe situations on the video measure than control children at posttesting. These gains were maintained at 6-week follow-up testing. There were no differences in treatment and control children's self-reported anxiety or parents' reports of negative emotional/behavioral consequences, which were minimal. Over 5% of participating children reported ongoing or past sexual abuse. In the One-Year Follow-Up Study, children's knowledge gains and prevention skills scores on the video measure were maintained at one-year follow-up. A 1-session "booster shot" program further enhanced children's safety discrimination skills on the video measure.     

Foods for health: Involving organizations in planned change

The development of effective strategies for planned change presents a challenge to an organization operating in a modern, complex society. A change agency often faces two barriers to the diffusion of innovations —the lack of direct contact with individual receivers on a daily basis, and limited and perhaps shrinking resources. Two strategies which help a change agency address these barriers are: a) the use of co‐change agencies in innovation development and b) the diffusion of innovations through other organizations at the system‐receiver level. The use and effectiveness of these modifications to the traditional diffusion model are illustrated in the development and diffusion of a health education program called Foods for Health.     

Efficacy of the Check & Connect Mentoring Program for At-Risk General Education High School Students

Although graduation rates are rising, the high school dropout problem remains a national crisis, and evidence-based information about interventions for at-risk students is critically needed. Prior research shows that Check & Connect, an individualized mentoring program, has positive effects on school persistence and progression for students with disabilities. This study examined the efficacy of Check & Connect with general education students who showed early warning signs of risk for dropping out of high school in a large urban district. The sample included 553 students with the lowest predicted probabilities of on-time graduation based on attendance, behavior, and course performance in Grades 8 and 9. Students were randomly assigned to receive a Check & Connect mentor for three years, starting in the summer after Grade 9, or not. Findings suggest the program was implemented with fidelity, except with students who left district schools. Check & Connect did not have any statistically significant impacts on measures of engagement, academic progress, the likelihood of dropping out, or graduation. These results are discussed in the context of other literature on mentoring and dropout prevention.

US preexposure: Effects on flavor aversions produced by pairing a poisoned partner with ingestion

If an unpoisoned rat drinks a flavored solution and then is exposed to another rat suffering from lithium poisoning, the unpoisoned rat will later exhibit a flavor aversion. This is called the poisoned partner effect (PPE). The present experiments showed that (1) the US preexposure effect applies to the PPE since, if the unpoisoned rat is preexposed to poisoned partners, the PPE is attenuated, (2) the magnitude of the PPE increases with the dose of poison, and (3) a poisoned partner accustomed to poisoning produces a slightly weaker PPE than a partner naive to poisoning. Two earlier findings were confirmed: (1) The PPE occurs because the poisoned partner is an aversive US, not because a learned aversion is transferred from one rat to another; and (2) the PPE is weaker than an aversion produced by poisoning itself.     

Using Retrospective Pre-Ratings to Counteract Response-Shift Confounding

A potential confounding effect present in research designs which employ self-report instruments is response-shift, i.e., a change in the internalized standard by which a subject rates himself. Howard et al. (6) suggest that when self-report measures must be used to measure behavioral changes there should be a modification of Campbell and Stanley’s design (2) so as to include a “retrospective pre-rating.” In the current research, the response-shift phenomenon is demonstrated in the context of a typical classroom setting. Retrospective pre-ratings are shown to yield significantly more accurate estimates of preinstruction knowledge than simple pre-ratings. However, there was no statistically significant difference between correlation co-efficients relating “behavioral change” and “self-reported change” when self-reported change was defined in terms of retrospective pre-ratings rather than in terms of simple pre-ratings.
