Measuring Growth in a Longitudinal Large-Scale Assessment with a General Latent Variable Model

The aim of the research presented here is the use of extensions of longitudinal item response theory (IRT) models in the analysis and comparison of group-specific growth in large-scale assessments of educational outcomes.     

There is no interest in precious stones in a vegetable market: the life and sermons of Rabbi Jacob Gordon of Toronto

A preliminary examination of Rabbi Jacob Gordon’s sermons within their biographical, communal, religious, historical, social, and cultural contexts, offers insight into the challenges Jewish immigrants faced in early twentieth century Toronto—as this Orthodox immigrant rabbi perceived them. These sermons provide details and perspectives, and they particularly illuminate doings within Toronto’s Orthodox-immigrant Jewish community. Gordon’s East-European background did not hold him back from remolding his style, as well as the content of his sermons, fully aware as he was of the need to modify his sermonic approach to respond to the novelties of Toronto’s immigrant world. Gordon’s sermons may also be compared to those of other North American contemporaries, again signaling the unique aspects of the Canadian Jewish religious experience at a critical moment. I am grateful to those who assisted in clarifying certain details and issues, as well as offered comments and criticism on early versions of this article: Michael Brown, Marilyn Budd, Richelle Budd Caplan, Avraham A. Greenbaum, Richard Menkis, Ira Robinson, Marc Saperstein, and Mordechai Zalkin. Valuable archival sources are located at the Canadian Jewish Congress Charities Committee National Archives, Montreal (CJC), and at the Ontario Jewish Archives (OJA), both of which I thank for their permission to cite documents in their possession, and I am especially indebted to Donna Bernardo-Ceriz and Janice Rosen for their assistance. Three technical notes are in order: 1) Books, articles or other sources in Hebrew or Yiddish which include an English title are cited in English, and those which do not have an English title were transliterated; 2) All the right pages in Gordon’s book are numbered and all the left pages are marked by Hebrew letters, both sequentially. The Hebrew letters and numbers are identical to the facing English ones. Therefore, whenever referring to the Hebrew letter pagination, I added HP—Hebrew pagination—in brackets; 3) The names of the following archival files in the Jacob Gordon Papers collection, CJC, are abbreviated as indicated in the brackets: Articles File (AF); Correspondence File (CF); and Press Clippings File (PCF).     

Increases in global and domain specific self-esteem following a 10 day developmental voyage

Although positive effects are often reported, research assessing the impact of Adventure Education and Outward Bound programmes on self-esteem is fraught with methodological weaknesses pertaining to an emphasis on scales assessing global self-esteem, a lack of follow-up measures to assess the potential long-term benefits of such programmes and inadequate pre-intervention measures. In a far less researched area of structured outdoor programmes, research using the sea and sailing ships as a medium, have suffered from the same weaknesses as many of their land-based counterparts. The current study sought to improve and extend on previous research in this broad area. In doing this global and multiple dimensions of self-esteem were assessed 3 weeks prior to a 10 day Spirit of New Zealand developmental voyage, on the first day of the voyage, the last day of the voyage, and finally, 3 months following the voyage. Two hypotheses were subsequently tested. The first stated that participants would experience increases in global and domain specific self-esteem following the voyage. The second stated that increases in global and specific domains of self-esteem would have a long-term effect (i.e. they will be in evidence 3 months following the last day of the voyage). Support was found for both hypotheses.     

Impact of Immigration on Economic Growth in Canada and in its Smaller Provinces

This paper evaluates the potential impact of education levels of immigrants and Canadian-born on economic growth in Canada and its smaller provinces by using data for the period 2006–2013. We specify a production function in which levels of educational attainments of immigrants and Canadian-born workers are entered separately. Feasible generalized least square (FGLS) method is applied to estimate the production function separately for all immigrants, and also for established immigrants (those who have been in Canada for 10 years or longer). The results show that all educational levels of immigrants have positive and statistically significant effects on economic growth. A similar conclusion applies to Canadian-born workers, although the impacts of their university degree holders is lower than that of immigrant university degree holders. Both immigrant and Canadian-born workers have smaller effects on economic growth in smaller provinces, which have attracted larger numbers of immigrants in recent years. The results also show that the economic growth effects are similar for all and established immigrants. Although these results are consistent with previous findings on discounting of immigrants’ educational credentials, more data are needed to strengthen their validity. We also suggest that the higher economic growth impact of immigrant university degree holders than that of Canadian-born is indicative of greater social returns to higher education resulting from increased diversity of population which in turn, as some previous studies suggest, can result in increased technological innovation, new ideas, and production of a wide variety of goods and services.     

Salience drives non-spatial feature repetition effects in cueing tasks

In an exogenous cueing task repeating a non-spatial feature can benefit performance if the feature is task-relevant to a discrimination response. Previous studies reporting this effect have used complex displays. In the current study, we look at the generalizability of this effect, by extending it to a simple exogenous cueing paradigm in which the cue and target displays each consist of single-object onsets. We also investigate the influence of task-relevant and irrelevant features independently within the same experiment. Consistent with previous studies, we find non-spatial feature repetition benefits in all three experiments. Importantly, and unlike previous studies, we find that the most salient, rather than the task-relevant, feature drives the non-spatial feature repetition benefit. Furthermore, in addition to the previously observed non-spatial feature repetition benefits, we also found a spatially specific feature repetition benefit. We argue that these new findings are consistent with habituation accounts of attentional cueing effects.     

Variable Neighborhood Search Heuristics for Selecting a Subset of Variables in Principal Component Analysis

The selection of a subset of variables from a pool of candidates is an important problem in several areas of multivariate statistics. Within the context of principal component analysis (PCA), a number of authors have argued that subset selection is crucial for identifying those variables that are required for correct interpretation of the components. In this paper, we adapt the variable neighborhood search (VNS) paradigm to develop two heuristics for variable selection in PCA. The performances of these heuristics were compared to those obtained by a branch-and-bound algorithm, as well as forward stepwise, backward stepwise, and tabu search heuristics. In the first experiment, which considered candidate pools of 18 to 30 variables, the VNS heuristics matched the optimal subset obtained by the branch-and-bound algorithm more frequently than their competitors. In the second experiment, which considered candidate pools of 54 to 90 variables, the VNS heuristics provided better solutions than their competitors for a large percentage of the test problems. An application to a real-world data set is provided to demonstrate the importance of variable selection in the context of PCA.     

The Barbour – Smith – Gilkey Paradox: Historical Relativity in Natural Science and Historical Religion

This paper is about the relation of historical relativity and religious certainty. To live in history and to live with historical relativity is to admit that we are subject to the limitations of creaturehood: we know right and wrong, truth and falsity, relative to our own time and place, history and culture, but we do not know any truth or right that is non-relative to time and place. The differences between historical and naturalistic discourses of explanation are radical, and usually overlooked by scientists.     

Ethics in 15 min per Week

The demand for science trainees to have appropriate responsible conduct of research instruction continues to increase the attention shown by federal agencies and graduate school programs to the development of effective ethics curriculums. However, it is important to consider that the main learning environment for science graduate students and post-doctoral research fellows is within a laboratory setting. Here we discuss an internal laboratory program of weekly 15-minute ethics discussions implemented and used over the last 3 years in addition to the graduate school’s program of scientific integrity training. During this time, the environment and culture within our laboratory has changed to place greater emphasis on the ethical implications of our own research and the research we evaluate. We still struggle with how to accurately assess this behavioral change; although, we present preliminary survey results on the evaluation and impact of this style of curriculum for ethics instruction in our laboratory.     

Variation in the Use of Pronouns as a Function of the Topic of Argumentation in Young Writers Aged 11 Years

In our view, the ability to impose moral values which may be, to some extent, either shared or conflictual, influences the strategy adopted when writing argumentative texts. Our hypothesis is that the greater the socio-moral distance between the writers’ representations (the writers in this case being children) and those of the recipients (here the parents), the more likely it is that writing will be successful. Three topics derived from a preliminary experiment and corresponding to significant differences in opinion between children and parents were tested in a population of 11-year-old pupils. The pupils had to write a letter designed to convince their parents about one of these topics. We analyzed the texts in order to identify the different configurations in the frequencies of use of the pronouns (frequencies of Je (I), Tu (You), Il (He), On (One/We)) and adverbs. These frequencies differed depending on the topic that was being written about (the moral context that is mobilized).

Relationship between sleep disturbance,depression and anxiety in the 12 months following a cardiac event

We aimed to assess the prevalence of sleep disturbance in a cardiac patient population over a 12-month period and assess its relationship with treatment adherence, self-efficacy, anxiety and depression. A total of 134 patients consecutively admitted to two Australian hospitals after acute myocardial infarction (31%), or to undergo bypass surgery (29%) or percutaneous coronary intervention (40%) were interviewed at six weeks and four and 12 months. Sleep disturbance was measured using a recode of the Beck Depression Inventory (v.2) item 16. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale. Sleep disturbance was highly prevalent (69%) at 6 weeks but was not associated with 12-month psychological outcomes. Path analysis revealed that sleep disturbance at 4 months was, however, associated with reduced treatment adherence and self-efficacy, and higher anxiety and depression scores at 12 months. The high prevalence of sleep disturbance in this study and its association with psychological outcomes may have adverse prognostic implications and possibly impede cardiac rehabilitation efforts.     

Sufficiency and Conditional Estimation of Person Parameters in the Polytomous Rasch Model

Rasch models are characterised by sufficient statistics for all parameters. In the Rasch unidimensional model for two ordered categories, the parameterisation of the person and item is symmetrical and it is readily established that the total scores of a person and item are sufficient statistics for their respective parameters. In contrast, in the unidimensional polytomous Rasch model for more than two ordered categories, the parameterisation is not symmetrical. Specifically, each item has a vector of item parameters, one for each category, and each person only one person parameter. In addition, different items can have different numbers of categories and, therefore, different numbers of parameters. The sufficient statistic for the parameters of an item is itself a vector. In estimating the person parameters in presently available software, these sufficient statistics are not used to condition out the item parameters. This paper derives a conditional, pairwise, pseudo-likelihood and constructs estimates of the parameters of any number of persons which are independent of all item parameters and of the maximum scores of all items. It also shows that these estimates are consistent. Although Rasch’s original work began with equating tests using test scores, and not with items of a test, the polytomous Rasch model has not been applied in this way. Operationally, this is because the current approaches, in which item parameters are estimated first, cannot handle test data where there may be many scores with zero frequencies. A small simulation study shows that, when using the estimation equations derived in this paper, such a property of the data is no impediment to the application of the model at the level of tests. This opens up the possibility of using the polytomous Rasch model directly in equating test scores.     

The Stroop test: A developmental study in a French children sample aged 7 to 12 years

The Stroop test is a commonly used task in psychology to assess executive function and more specifically inhibition. International studies consistently show improved Stroop task performance with age, whereas available French normative data displays the opposite pattern, with poor clinical sensibility (Albaret & Migliore, 1999). To provide an alternative and useful Stroop test for children, we examined developmental data based on a well-known French protocol validated in adult (GREFEX study group, 2001). The three-standard conditions of the Stroop task (i.e. naming, reading and interference) were administered to 120 typically developing school children (7–12 years), while taking into account the effects of gender, parental educational level and intelligence (both crystallized and fluid intelligence, as measured by the Wechsler intelligence scale). The time to complete each condition (in seconds) was recorded, as well as the number of uncorrected and corrected errors. Results show a continuous increase of performance in “reading” and “naming” control conditions between 7 and 12 years, suggesting an improvement in the lexical access speed and the automation of decoding abilities during reading. Most importantly, a significant reduction of time Stroop effect with age was found (difference between interference and naming conditions), but no interaction with gender. Stroop performances are related to fluid intelligence once age is statistically controlled, but not to parental educational level. The developmental pattern found from the Stroop GREFEX version is consistent with international data and more broadly with executive function and inhibition development. These findings open the prospect of useful normative standardization of this task, with valuable clinical applications perspectives.     

Type D Personality in the Prediction of Internet Addiction in the Young Adult Population of Slovak Internet Users

This article presents the results of the first study on the relationship between Internet addiction (IA) and Type D personality (D is for distressed) in Slovakia and is the first attempt to examine the impact of Type D personality in the prediction of IA beyond personality dimensions. Altogether 405 adult Slovak Internet users (aged from 18 to 45 years) filled out the following questionnaires: IRPS, DS14, and NEO-FFI. The results showed that there wasn’t a significant effect of the Type D personality on levels of IRPS after controlling for the effect of Big-Five personality traits. The Big Five personality dimensions and demographics explained 21.1 % of variance in IA. According to our results the typical adult addicted to the Internet could be characterized as a young introverted unconscientious and disagreeable neurotic. Future research should concentrate more on the creation and validation of the model of IA.     

Bringing culture to the nation: Hebraism, Yiddishism, and the dilemmas of Jewish cultural formation in Russia and Ukraine, 1917–1919

Focusing on the pivotal 1917–1919 conjuncture in Russia and Ukraine, this paper analyzes the efforts of the divided Jewish nationalist intelligentsia to disseminate new forms of Jewish culture to a mass audience, the reception of these efforts in the former Tsarist empire’s variegated Jewish population, and the intelligentsia’s parallel exploration of other forms of cultural formation less dependent on popular support. Comparing the cultural programs of Hebraism and Yiddishism, it demonstrates important parallels in their cultural visions and highlights their shared belief in the possibility of implanting a secularist, aestheticist intelligentsia culture in the whole of “the nation.” The paper reconstructs both substantial forms of popular openness to this culture and its sociocultural weaknesses. Finally, it examines experiments made by the intelligentsia with alternative routes to cultural transformation: suppression of popular culture, non-market cultural arrangements, cultural revolution through education, and the uses of the state. The paper seeks a fuller understanding both of the roots of interwar cultural programs in Eastern Europe and the Soviet Union, and of the Jewish nationalist intelligentsia’s underlying conception of “culture,” its own authority, and the evolving relationship between these conceptions and the realities of East European Jewish social, cultural, and political life from the 1890s onward.     

25 years of research on the use of geometry in spatial reorientation: a current theoretical perspective

The purpose of this article is to review and evaluate the range of theories proposed to explain findings on the use of geometry in reorientation. We consider five key approaches and models associated with them and, in the course of reviewing each approach, five key issues. First, we take up modularity theory itself, as recently revised by Lee and Spelke (Cognitive Psychology, 61, 152–176, 2010a; Experimental Brain Research, 206, 179–188, 2010b). In this context, we discuss issues concerning the basic distinction between geometry and features. Second, we review the view-matching approach (Stürzl, Cheung, Cheng, & Zeil, Journal of Experimental Psychology: Animal Behavior Processes, 34, 1–14, 2008). In this context, we highlight the possibility of cross-species differences, as well as commonalities. Third, we review an associative theory (Miller & Shettleworth, Journal of Experimental Psychology: Animal Behavior Processes, 33, 191–212, 2007; Journal of Experimental Psychology: Animal Behavior Processes, 34, 419–422, 2008). In this context, we focus on phenomena of cue competition. Fourth, we take up adaptive combination theory (Newcombe & Huttenlocher, 2006). In this context, we focus on discussing development and the effects of experience. Fifth, we examine various neurally based approaches, including frameworks proposed by Doeller and Burgess (Proceedings of the National Academy of Sciences of the United States of America, 105, 5909–5914, 2008; Doeller, King, & Burgess, Proceedings of the National Academy of Sciences of the United States of America, 105, 5915–5920, 2008) and by Sheynikhovich, Chavarriaga, Strösslin, Arleo, and Gerstner (Psychological Review, 116, 540–566, 2009). In this context, we examine the issue of the neural substrates of spatial navigation. We conclude that none of these approaches can account for all of the known phenomena concerning the use of geometry in reorientation and clarify what the challenges are for each approach.     

Re-work: a new Japanese support system for reinstatement

Re-work is a new treatment technique that follows the conventional Japanese approach, which includes rest and pharmacotherapy. The aim of re-work is to prevent repeated sick leave by helping individuals reflect on the reasons behind the sick leave and improve stress-related coping skills. Re-work participants prepare in an environment similar to their workplaces at a medical institution or a specialised public facility for several months before returning to work. As re-work is undertaken via group work, this has benefits beyond those which can be achieved by an individual alone. The reinstatement effects of re-work are now starting to be verified. Issues of interest for re-work include its unified concept-based programme, and the need to further verify its clinical efficacy and cost-effectiveness.     

What's in a smile?

In positive social contexts, both adults and older infants show more Duchenne smiling (which involves high cheek raising) than non-Duchenne smiling (which does not). This study compared Duchenne and non-Duchenne smiles in early infancy for clues to their emotional significance. Infants (N = 13) from 1 to 6 months of age were videotaped weekly for 5 min in 208 face-to-face interactions with their mothers. Levels of Duchenne and non-Duchenne smiling were correlated within interactive sessions, and the 2 smiles had similar developmental trajectories. Duchenne smiles were typically preceded by non-Duchenne smiles. The results suggest these frequently contrasted types of smiles occur in similar situations and are often different temporal phases of a continuous emotional process. In contrast to adults, infant Duchenne smiles had longer durations than non-Duchenne smiles, suggesting infant smiling does not fit adult models of emotional functioning.     

What's in a Name?

This paper is about the mode of being of names. The paper begins by explaining why the joke is on commentators who see Lewis Carroll's White Knight as applying the use/mention distinction. Then it argues that the real problem with the distinction is that the idea that names are used to mention what they name depends on mistakenly conceiving of language as existing autonomously; and that philosophers have this conception because they fail to appreciate what they are doing when they philosophise about language. This failure also explains why philosophers mistakenly think of any manifestation of a name as a (physical) token.
