Teaching Social and Emotional Competence in Early Childhood
This study evaluated the impact of a social skills curriculum on the social behaviors of students in two pre-kindergarten classrooms. Participating were 30 students in a program based at a university child study center. The average age of the participants was four years ten months. The income levels of the families varied from low social economic status to high middle economic status. Two examiners independently completed the Social Skills and Attitude Scale (SSAS) for each child. The examiners observed the children and recorded children\u27s pre and post intervention behaviors on a checklist. The study yielded positive evidence that the social skills instruction and activities in the Connecting with Others: Lessons for Teaching Social and Emotional Competence did make a meaningful difference. Paired sample t-tests were run on all Pre:/Post: test pairs in order to measure significant change in social skills behaviors over the course of the intervention. With the exception of Shares ideas, t-test results indicate significant change in social skills on all but one of the pretest/posttest pairs

General Interviewer Techniques: Developing Evidence-Based Practices for Standardized Interviewing
The practices of standardized interviewing developed at many research sites over many years. The version of standardization that Fowler and Mangione codified in Standardized Survey Interviewing has provided researchers a core resource to use in training and supervising standardized interviewers. In recent decades, however, the accumulation of recordings and transcripts of interviews makes it possible to re-visit the practices of standardization to describe both how respondents actually answer survey questions and how interviewers actually respond.
To update General Interviewer Training (GIT), we brought observations of interaction during interviews together with research about conversational practices from conversation analysis, psychology, and other sources. Using our analysis of the question-answer sequence, we identified the principal actions covered in training as reading a survey question, recognizing a codable answer, acknowledging a codable answer, and follow-up for an uncodable answer. Our analysis of each of these actions is influenced by our observations of the participantsâ behavior â interviewers must be trained how to repair the reading of the question, for example -- and by how that behavior is influenced by characteristics of survey questions â follow-up differs for yes-no and selection questions. We developed a set of criteria to use in evaluating the likely impact of the choices we recommend on, for example, interviewer variance and the motivation of the respondent. Although research is not available for all (or even most) criteria, we attempted to be systematic in assessing the likely costs and benefits of our decisions.
We focus on standardized interviewing, which attempts to train interviewers in behaviors that all interviewers can perform in the same way. However, the evidence supplied by studies of interviewer-respondent interaction makes clear that the impact of the question on the respondentâs answer, and the way that respondents answer questions must be taken into account in any style of interviewing

Reprint of âAtlantic Multidecadal Oscillation (AMO) modulates dynamics of small pelagic fishes and ecosystem regime shifts in the eastern North and Central Atlanticâ
Dynamics of abundance and migrations of populations of small pelagic clupeoid fish such as anchovy (Engraulis encrasicolus), sardine (Sardina pilchardus), sardinella (Sardinella aurita), sprat (Sprattus sprattus) and herring (Clupea harengus) in the eastern North and Central Atlantic between Senegal and Norway vary in synchrony with the warm and cool phases of the Atlantic Multidecadal Oscillation (AMO). This is shown by compiling retrospective data on fish catches and anecdotal observations, which in some cases date back to the mid-19th century. The AMO is defined as the de-trended mean of North Atlantic (0-60 degrees N) sea surface temperature anomalies. However, it is not primarily the temperature which drives the dynamics of the small pelagic fish populations. Instead, the AMO seems to be a proxy for complex processes in the coupled atmosphere-ocean system of the North Atlantic. This is manifested in large-scale changes in strength and direction of the current system that move water masses around the North Atlantic and likely involves the North Atlantic Oscillation (NAO), the Atlantic Meridional Overturning Circulation (AMOC), the Mediterranean Overflow Water (MOW) and the subpolar gyre (SPG). The contractions and expansions of the SPG apparently play a key role. This was particularly obvious in the mid-1990s, when the SPG abruptly contracted with the result that warm subtropical water masses moved to the north and east. Small pelagic fish populations in the eastern North and Central Atlantic, including those in the Mediterranean responded quickly by changing abundances and migrating northwards. It seems that the complex ocean-atmosphere changes in the mid-1990s, which are described in the text in detail, caused a regime shift in the ecosystems of the eastern North and Central Atlantic and the small pelagic clupeoid fish populations are the sentinels of this shift
Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans
Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have
fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in
25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16
regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of
correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP,
while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in
Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium
(LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region.
Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant
enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the
refined data for existing association signals, we estimate that these loci now explain âŒ38.9% of the familial relative risk of PrCa,
an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of
PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent
signals within the same regio
The effects of problem-oriented policing on crime and disorder
Problem-oriented Policing (POP) was first introduced by Herman Goldstein in 1979. The
approach was one of a series of responses to a crisis in effectiveness and legitimacy in
policing that emerged in the 1970s and 1980s. Goldstein argued that police were not
being effective in preventing and controlling crime because they had become too focused
on the âmeansâ of policing and had neglected the âgoalsâ of preventing and controlling
crime and other community problems. Goldstein argued that the unit of analysis in
policing must become the âproblemâ rather than calls or crime incidents as was the case
during that period. POP has had tremendous impact on American policing, and is now
one of the most widely implemented policing strategies in the US.
To synthesize the extant problem-oriented policing evaluation literature and assess the
effects of problem-oriented policing on crime and disorder
Eligible studies had to meet three criteria: (1) the SARA model was used for a problemoriented
policing intervention; (2) a comparison group was included; (3) at least one
crime or disorder outcome was reported with sufficient data to generate an effect size.
The unit of analysis could be people or places.
Several strategies were used to perform an exhaustive search for literature fitting the
eligibility criteria. First, a keyword search was performed on an array of online abstract
databases. Second, we reviewed the bibliographies of past reviews of problem-oriented
policing. Third, we performed forward searches for works that have cited seminal
problem-oriented policing studies. Fourth, we performed hand searches of leading
journals in the field. Fifth, we searched the publications of several research and
professional agencies. Sixth, after finishing the above searches we e-mailed the list of
studies meeting our eligibility criteria to leading policing scholars knowledgeable in the
area of problem-oriented policing to ensure we had not missed any relevant studies.
For our ten eligible studies, we provide both a narrative review of effectiveness and a
meta-analysis. For the meta-analysis, we coded all primary outcomes of the eligible
studies and we report the mean effect size (for studies with more than one primary
outcome, we averaged effects to create a mean), the largest effect, and the smallest effect.
Because of the heterogeneity of our studies, we used a random effects model.
Based on our meta-analysis, overall problem-oriented policing has a modest but
statistically significant impact on reducing crime and disorder. Our results are consistent
when examining both experimental and quasi-experimental studies.
Conclusions:
We conclude that problem-oriented policing is effective in reducing crime and disorder,
although the effect is fairly modest. We urge caution in interpreting these results because
of the small number of methodologically rigorous studies on POP and the diversity of
problems and responses used in our eligible studies
Long-term variability of the siphonophores Muggiaea atlantica and M. kochi in the Western English Channel
We investigated long-term variability of the calycophoran siphonophores Muggiaea atlantica and Muggiaea kochi in the Western English Channel (WEC) between 1930 and 2011. Our aims were to describe long-term changes in abundance and temporal distribution in relation to local environmental dynamics. In order to better understand mechanisms that regulate the speciesâ populations, we identified periods that were characteristic of in situ population growth and the environmental optima associated with these events. Our results show that between 1930 and the 1960s both M. atlantica and M. kochi were transient components of the WEC ecosystem. In the late 1960s M. atlantica, successfully established a resident population in the WEC, while the occurrence of M. kochi became increasingly sporadic. Once established as a resident species, the seasonal abundance and distribution of M. atlantica increased. Analysis of environmental conditions associated with in situ population growth revealed that temperature and prey were key determinants of the seasonal distribution and abundance of M. atlantica. Salinity was shown to have an indirect effect, likely representing a proxy for water circulation in the WEC. Anomalies in the seasonal cycle of salinity, indicating deviation from the usual circulation pattern in the WEC, were negatively associated with in situ growth, suggesting dispersal of the locally developing M. atlantica population. However, our findings identified complexity in the relationship between characteristics of the environment and M. atlantica variability. The transition from a period of transiency (1930â1968) to residency (1969â2011) was tentatively attributed to structural changes in the WEC ecosystem that occurred under the forcing of wider-scale hydroclimatic changes
