description: The growing sophistication of research on diversity in organizations parallels the evolution of organizations into increasingly complex and dynamic forms. As teams interact with other teams, the organizational context in which teams operate can create opportunities as well as pose challenges for team functioning . In this chapter, we consider how the demographic characteristics of the organizational context influences teamwork and so attempt to contribute to the academic discourse on diversity in two ways. First, we draw attention to the intrinsic value of diversity in relation to a team's external relationships. To meet organizational goals, each team must be effective in terms of its internal functioning . In addition, each team must effectively manage its relationships with other teams and individuals in the organization Through their relationships, team members may gain access to needed resources and exert influence that is beneficial to the team and its individual members. Past research, grounded in social psychological theory, has focused on the negative relationship between team diversity and internal team processes such as team cooperation. We recognize that an additional component of team functioning is relationships between teams. Based on social psychological theory, we argue that diversity in teams will be manifested in cooperative behaviors between teams in organizations .
title: The Perils of Judicial Restraint: How Judicial Activism Can Help Evolve the International Court of Justice
Creators: name: Mawar, Deepak
Publisher: name: Institut für Völker- und Europarecht, Georg-August-Universität Göttingen
Year: 2019

description: The article analyzes the International Court of Justice and its approach to judicial decision-making. By investigating the Court’s jurisprudence over its seventy years of activity, the article seeks to outline, that if given the choice, the ICJ tends to prioritize judicial restraint over judicial activism. In fact, the Court maintains a strict adherence to judicial restraint, which stems from a fear of losing its legitimacy when facing the issue of consent-based jurisdiction. The article purports that although judicial restraint is an important facet of sound judicial decision-making, the ICJ should not be so reluctant to adopt judicial activism when it is suitable to utilize such an approach. Such a position is strengthened when analyzing the criticisms made of judgments delivered by the Court, which fail to serve the international community beneficially.

description: This paper deals with an application of non parametric multivariate permutation methods (Pesarin, 1992, 1997, 1999) for the comparison of cancer growth patterns in animal models. The analyzed data come from an experiment whose purpose consists of revealing the anticancer activity of a new taxol synthetic drug. We are interested in testing if the growth inhibition effect due to treatment is statistically significant. To compare treated with untreated growths we face some multivariate testing problems related with repeated measures. A parametric approach for the solution of these hypotheses testing problems is not possible because in our case the number of observed units is less then the number of repeated measures.

Frugal Methods for the Independent Set and Graph Coloring Problems.
Creators: name: Halldorsson, Magnus M.
Publisher: name: Rutgers University
Year: 1991

description: We consider two classical hard graph problems: finding the maximum independent set of vertices, and coloring the vertices with fewest colors possible. We are interested in frugal algorithms for these problems, ones that use limited amount of computing capabilities. Such algorithms yield approximate, rather than exact, solutions, and are valued according to their performance guarantee, which is the maximum factor that approximate solutions can differ from optimal ones. We are primarily interested in two classes of frugal algorithms: polynomial-time, and on-line algorithms. We present several polynomial-time algorithms for obtaining large approximations in graphs containing large independent sets, and use them to improve the best performance guarantees known for both problems. We show how nearly all effective algorithms for these problems fall into yet another category of frugal algorithms, based on removing subgraphs, and obtain tight lower bounds on their performance. For on-line graph coloring, we give strong lower bounds for both deterministic and randomized algorithms, that hold even if the models are weakened in several ways, and improve the best performance guarantee known for randomized on-line coloring. Finally, we prove simple tight bounds on two interpretations of the on-line independent set problem and some of its variations.
Some aspects of principal components analysis as measurement error model

description: In this paper , Principal Component Analysis  (PCA) is formulated within a likelihood framework, based on a specific form of Gaussian model. We suggest how the principal axes of observed data vectors may be determined through maximum-likelihood estimation of parameters in a latent variable  model closely related to a Factor Analysis and Error-in-Variables Models. We consider the properties of the associated likelihood function and discuss the advantages conveyed by the definition of a probability density function for PCA. The numeric/graphical quantities of the usual output now represent the maximum likelihood estimates of the parameters of a probabilistic model, rather than approximations of an algebraic-geometric algorithm. The use of PCA as method of analysis communicated by the interpretation of the principal components: we determine the subdivision a posteriori predictors of redundant variables. We investigate the proposed model in a case-control study of cardiovascular disease.

description: This paper deals with the CUMINCAD-repository (Cumulative Index on CAD), which was set up in 1998 and has served the CAAD-community since then as an important source of archived domain related information. CUMINCAD contains over 5,000 entries in the form of publications in the field of Computer Aided Architectural Design. The number has been growing steadily over the years. To date only advanced search mechanisms have been provided to access these works. This may work out well for a just-in-time location of a reference but, is inadequate for just in case browsing through the history of CAAD. For such applications, a hierarchical browsing interface, like one in Yahoo or DMOZ.org is envisioned. This paper describes how the keyword categories were defined and how a moderate, distributed effort in defining the categories will allow machine-identified classification of the entire data set. The aim of the paper is to contribute to building up a wide spread consensus on what the appropriate keyword categories in CAAD are, and what sub-topics should sit below the main keyword categories.

description: Let us consider k populations having p-variate normal distributions with a cammon variance-convariance matrix where the parameters are known. Let X denote the vector of observations on an axperimental unit, of which the origin is uncertain. The problem of allocating X to one of the k given populations is fundamental in multivariate analysis. In many applications , it is also interesting to determine  whether X is related to a new population or not. This paper proposes a new  test of typicality in linear discriminant analysis. simulation were performed to check the level and the power of the test when the mean and the variance have to be evaluated  from the data.

description: The history of literary study is primarily remembered as a story of conflicting ideas. Many important kinds of change are left out of that story, because they happened gradually or failed to crystallize in a conscious methodological debate. New analytical approaches, like topic modeling, can illuminate those "quiet transformations," revealing that concepts taken for granted as the bedrock of literary studies are both more recent and more variable than scholars commonly assume.
The econometrics of consumption risk sharing: a new perspective

Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: In this paper it is proposed a new time series-based approach for testing consumption risk sharing among a set of counties or regions where both the long run and short run dynamic implications of the theory are simultaneously investigated within a Vector Equilibrium Correction (VEqC) model. This allows to measure whether countries or regions insure the non-aggregate uncertainty in their resources not only with respect to transitory shocks but also with respect to permanent ones . It is suggested that conventional risk sharing test have to be properly redefined to account for the possibility of error correcting dynamics and to avoid the possibility of "endogenous regressor bias" phenomena.

description: The scientific publication process has been so far only marginally affected by the possibilities of the Internet. This may be attributed to a lack of sound business models and pilots to demonstrate the ultimate benefits of free scientific publication. A team of universities, Internet publishers and applied research institutes proposes in the framework of the SciX-project (open, self-organizing repository for scientific information exchange) to demonstrate these benefits and re-engineer parts of the scientific publication process. This contribution focuses on the findings from investigations into the identification and acquisition of content sources - such as conference papers, theses and journal papers - related to the field of CAAD. Special attention has been paid to the different types of available information, such as bibliographical data, summaries, full texts, etc. In this paper, an overall estimation concerning the expected scientific output in the field of CAAD (within a midterm perspective), and the dissemination of already fully digitally stored publications as well as procedures (with financial figu-res) for retrospective digitalization of paper-based pu-blications will be presented. The workflow concerning digitalization and conversion was studied, as different levels of output are feasible.

The formula obtained is the generalization of Lloyd and Berry’s [Proc. Phys. Soc. London 91, 678–688 (1967)], the latter being limited to fluid host media, and it is the three-dimensional counterpart of that derived by Conoir and Norris [Wave Motion 47, 183–197 (2010)] for cylindrical scatterers in an elastic host medium.

description: The aim the present study is to develop a Bayesian reliability model using a new loss function that has been introduced by Higgins and Tsokos. The underlyng failure model is the exponential and four priors are being used: the inverted gamma , the general uniform, the exponential and the lognormal. The concept of efficienncy along with the notion of integrated mean square are being used as a criterion to analytically and numerically compare our findings with respect to the natural conjugate prior. It is shown that the Bayesian reliability estimates are in general sensitive to the choice of the prior probability distribution.

description: Digital screens have become an integral part of everyday life. In the wake of the digital swell, pre-adolescents and their parents are learning to navigate seemingly new terrain regarding digital media use. The present study aimed to investigate parent and pre-adolescent perceptions of screen use and the source of conflict surrounding digital media. We employed a qualitative thematic analysis of 200 parent and pre-adolescent dyads discussing screen use. Our analysis showed five overarching themes for screen use perceptions and conflict: screen time, effects of screen use, balance, rules, and reasons for screen use. In contrast to previous studies that mainly focused on parental perceptions, we were also able to shed light on pre-adolescent perceptions of screen use and the difference in opinions with their parents. Furthermore, we found that patterns of the source of screen use conflict were oftentimes rooted in the age-old developmental tug of war between autonomy-seeking pre-adolescents and authority-seeking parents. Though navigating autonomy-granting and seeking behavior is familiar to developmental scientists, negotiating these challenges in a new digital world is unfamiliar. Autonomy support, open dialogue, and playful interaction between parents and children are needed to understand and resolve conflict of digital media use in family contexts.
The effect of pre-post differences in walking, health, and weight on retirees’ long-term quality of life

Year: 2020
Subjects: Retirement; Walking; Health; Weight; Quality of Life; Self-monitoring

description: This research examined the effect of pre-post differences in walking duration, health, and weight on retirees’ long-term quality of life (QoL). It used data from a 2018 randomized mail survey of 483 suburban New Jersey retirees. Ordinary least squares (OLS) and three-stage least squares (3SLS) models were used. The analysis showed that changes in walking duration during the first two years of retirement are directly associated with health change, health change has an effect on long-term QoL, and weight variation of 10 lbs or more has an effect on health change and long term QoL. Although QoL peaks for the sample of retirees at around age 75, people whose average walking duration increased, health improved, and weight did not increase substantially after retirement continued to experience high QoL for a longer time. The results show that people can achieve high long-term QoL by choosing an active lifestyle when transitioning to retirement.

description: Characterizing the quantity and nutritional quality of food products in consumers’ homes is important to developing programs to educate consumers on healthy dietary habits and increasing healthy food availability. It has been well-documented that the availability of healthy food directly contributes to the quality of a diet. However, obtaining an accurate picture of food stored in the home for everyday use can be extremely difficult. Self-reports by consumers and estimations derived from food-frequency questionnaires typically have significant margins of error. Traditional line-item written records have shown to be accurate but time consuming. Therefore, estimating the nutritional adequacy of household food supplies is quite difficult and new technological approaches may be warranted. Recent research comparing Universal Product Code (UPC) scanning and traditional line-item recording found that UPC scanning produced a 32% times savings while also having 95.6% accuracy.1 UPC scanning to conduct household kitchen audits is a new novel methodology that can be used to obtain an accurate picture of food stored in the home. The objective of this study is to provide an accurate assessment of the caloric and nutrient content of household food inventories of Oaxacan and African-American households and also to compare and contrast findings from previous kitchen audits conducted in a reference sample of households of varying socioeconomic status (SES).

What’s in an Attribute? Consequences for the Least Common Subsumer
Creators: name: Küsters, Ralf
name: Borgida, Alex
Publisher: name: Rutgers University
Year: 1997

description: Functional relationships between objects, called ``attributes'', are of considerable importance in Knowledge Representation and Reasoning schemes, including Description Logics (DLs). A study of the literature indicates that papers have made, often implicitly, different assumptions about the nature of attributes: whether they are always required to have a value, or whether they can be partial functions. The work presented here is the first explicit study of this difference for subclasses of the Classic DL, involving the same-as concept constructor. It is shown that although determining subsumption between concept descriptions has the same complexity (though requiring different algorithms), the story is different in the case of determining the least common subsumer (lcs). For this operation, the lcs exists and can be computed relatively easily when attributes are partial; even in this case our result correct and extend three previous papers about the lcs of DLs. For total attributes, the lcs may not exist, and even if it exists it may be of exponential size. Interestingly, it is possible to decide in polynomial time if the lcs exists.

description: Modular co-culture engineering is an emerging approach for biosynthesis of complex natural products. In this study, we constructed microbial co-cultures composed of two and three E. coli strains, respectively, for de novo biosynthesis of flavonoid acacetin, a value-added natural compound possessing numerous demonstrated biological activities, from simple carbon substrate glucose. To this end, the heterologous biosynthetic pathway was divided into different modules, each of which was accommodated in a dedicated E. coli strain for functional expression. After the optimization of the inoculation ratio between the constituent strains, the engineered cocultures showed a 4.83-fold improvement in production comparing to the mono-culture controls. Importantly, cultivation of the three-strain co-culture in shake flasks resulted in the production of 20.3 mg/L acacetin after 48 h. To our knowledge, this is the first report on acacetin de novo biosynthesis in a heterologous microbial host. The results of this work confirm the effectiveness of modular co-culture engineering for complex flavonoid biosynthesis.

description: The Bush Administration has implemented more reforms to the regulatory process than any of its predecessors. These reforms are often stereotyped as anti-regulatory. This article examines the reforms as a whole and asks which interests have been empowered by the Bush Administration regulatory reforms. I believe this method is a more effective way of assessing the impact of the reforms. I find that in addition to adding potential costs to the regulatory process, the reforms are likely to empower powerful interest groups and the presidency. Whether the impact of these reforms is pro-regulation or anti-regulation will depend on how a future administration more dedicated to regulatory protections uses them. I also lay out a research agenda to better empirically assess the impact of these regulatory reforms.

description: This paper explores the problems arising when the reduced form cointegrating vectors are obtained from an incomplete VAR with omitted endogenous variables. It is shown that an incomplete VAR model, based on variables of the long-run reduced forms, produces an approximation of the cointegrating vectors coefficients and the misspecification of the short-run dynamics. It is also shown that this problems do not arise in certain circumstances. An example concerning the estimation of the NAIRU is provided suggesting the empirical relevance of our criticism.

description: This study reviewed the Learning for Community Empowerment Project (LCEP-2), a five-year project designed by UN-Habitat and funded by the United States International Agency for Development (USAID). The project’s major goal was to empower marginalized communities in Afghanistan through activities in integrated literacy, community saving and investment groups, apprenticeships, and business development training. The study examined the empowerment model of this project. It first investigated the work the social organizers did with the men and women residents of the project implementation locations in transforming patriarchal norms in conservative areas to improve women’s access to public space. It then looked at the impact of literacy and apprenticeship training on women’s social and economic lives. The study found that these social organizers, who were the front-line soldiers of the project, played a significant role in influencing the patriarchal institutions to encourage capacity development opportunities for women in the villages. It also found that this kind of community mobilization, which is crucial for the successful establishment of women’s empowerment programs, especially in conservative areas, is viewed as a secondary need by program design stakeholders and donors. High-level stakeholders often pay more attention to the project implementation stage and any tangible outcomes such as number of students enrolled, number of teachers trained, and number of schools established. Regarding the LCEP-2 empowerment model itself, in total, the study revealed that the model played a crucial role in the social empowerment of women. However, it produced mixed results in regards to improving the economic lives of women. The majority of women who were enrolled in the apprenticeship training struggled in marketing their products due to patriarchal norms and the crippling economy in the country. The study suggested that Afghanistan should institutionalize the social organizers’ roles and the community mobilization process within its larger development framework by allocating sufficient resources and including them in any of its rural development activities. The study also recommends that program designers and policymakers involve social organizers in the design of women’s empowerment projects. This step will help to reduce gaps between policy and practice. Additionally, the study concluded that livelihood training, which in certain situations is more effective than apprenticeship training, has the potential for successful growth in rural communities.

description: Given atmospheric measurement from a network of monitoring sites in the area of a city and over an extended period of time, an important problem is to identify the spatial and temporal structure of data. In this paper we focus on the identification and estimate of a statistical model to analyse the SO2 in the city of  Padua, where data are collected by some fixed stations and some mobile stations moving without any specific rule in different new locations, staying in every location for a variable number of days. The proposed method divides the global variability in large scale and small scale using some stochastic process as component of variability. The estimate is provided using a state space formulation of the model.
As applications of the model we propose the spatial and temporal prevision of the concentration of  SO2 . Finally, an exercise is proposed to choose an optimal network for the mobiles monitoring stations for a fixed future time.

description: Learning of large-scale networks of interactions from microarray data is an important and challenging problem in bioinformatics. A widely used approach is to assume that the available data constitute a random sample from a multivariate distribution belonging to a Gaussian graphical model. As a consequence, the prime objects of inference are full-order partial correlations which are partial correlations between two variables given the remaining ones. In the context of microarray data the number of variables exceeds the sample size and this precludes the application of traditional structure learning procedures because a sampling version of full-order partial correlations does not exist. In this paper we introduce a structure learning procedure, that we call the qp-procedure, based on limited-order partial correlations. The procedure is implemented in a freely available package for the statistical software R.

description: Integrating technology into agricultural systems has gained considerable traction, particularly over the last half century. Agricultural systems that incorporate the public’s concerns regarding farm animal welfare are more likely to be socially accepted in the long term, a key but often forgotten component of sustainability. Gene editing is a tool that has received considerable attention in the last five years, given its potential capacity to improve farm animal health, welfare, and production efficiency. This study aimed to explore the attitudes of Brazilian citizens regarding the applications of gene editing in cattle that generate offspring without horns; are more resistant to heat; and have increased muscle tissue. Using a mixed-methods approach, we surveyed participants via face-to-face, using in-depth interviews (Study 1) and an online questionnaire containing closed-ended questions (Study 2). Overall, the acceptability of gene editing was low and in cases where support was given it was highly dependent on the type and purpose of the application proposed. Using gene editing to improve muscle tissue growth was viewed as less acceptable compared to using gene editing to reduce heat stress or to produce hornless cattle. Support declined when the application was perceived to harm animal welfare, to be profit motivated or to reinforce the status quo of intensive livestock systems. The acceptability of gene editing was reduced when perceptions of risks and benefits were viewed as unevenly or unfairly distributed among consumers, corporations, different types of farmers, and the animals. Interviewees did not consider gene editing a “natural” process, citing dissenting reasons such as the high degree of human interference and the acceleration of natural processes. Our findings raised several issues that may need to be addressed for gene editing to comply with the social pillar of sustainable agriculture.

description: In this paper we study the properties of a family of index, called CI. These indices have
been proposed by Civardi, Zavarrone (2003) in order to evaluate the teaching quality in
university disciplines. The most frequently used scales offer four or five points and the
first two (or the last two) points on both scales are associated with negative evaluations
and the last two (or the first two) are associated with symmetric positive evaluations.
The empirical distribution of responses represents the starting point to compute the CI
indices. Each index assumes values lying between –100 (in the case of maximum negative
evaluation) to +100 (in the case of an evaluation of absolute excellence) and is obtained as
the algebraic sum of two indices. The first expresses the score obtained in the semi-plane
of positive evaluations while the second represents the score obtained in the semi-plane
of negative evaluations.
The CI index is characterized by the choice of the parameter of importance level k
(0?k?1) on the degree of importance the “investigator/decision maker” wants to assign
to the quota of very positive opinions and of the very negative ones.
The construction of the universe of response models of N respondents (with
10?N?105) and, for each distribution, of the eleven CI indices (k=0, 0.1, ..., 0.9, 1)) allow
to study the properties of effective distributions of the indices. The results highlight that
all effective distributions, varying N and k, are symmetric with mean, mode and median
equal to zero. The square mean error assumes values from 53 (when N=10 and k=0) to
31. The possibility of approximating CI distribution with a normal one offers interesting
developments in an inferential framework.

description: The scattering of radiation from collimated irradiation is accurately treated via normalization of phase function. This approach is applicable to any numerical method with directional discretization. In this study it is applied to the transient discrete-ordinates method for ultrafast collimated radiative transfer analysis in turbid media. A technique recently developed by the authors, which conserves a phase-function asymmetry factor as well as scattered energy for the Henyey–Greenstein phase function in steady-state diffuse radiative transfer analysis, is applied to the general Legendre scattering phase function in ultrafast collimated radiative transfer. Heat flux profiles in a model tissue cylinder are generated for various phase functions and compared to those generated when normalization of the collimated phase function is neglected. Energy deposition in the medium is also investigated. Lack of conservation of scattered energy and the asymmetry factor for the collimated scattering phase function causes overpredictions in both heat flux and energy deposition for highly anisotropic scattering media. In addition, a discussion is presented to clarify the time-dependent formulation of divergence of radiative heat flux.

description: The aim of this article is to reconstruct the historical trend of heights of conscripts
born in the province of Friuli in the years 1846-90. This work is dedicated to identifying
the problems encountered when using enrolment lists and to proposing solutions which
can, at least in part, correct these problems. Particular interest is posed in evidencing the
very high importance of using homogeneous measurements and in introducing some
techniques which have allowed us to render statures uniform and therefore also comparable
over time. The results obtained bring to light some possible weak points of the series
of Italian historical heights which has been used up to date.

Thematic analysis

description: Numerous studies demonstrate that lesbian, gay, bisexual, and transgender (LGBT) children and youth are likely to experience abuse by peers, parents, and other adults and that these experiences correlate with a host of mental health problems. However, there is little understanding of the experiences of LGBT children and youth living in countries where social and legal protections for sexual and gender minorities are limited or nonexistent. This qualitative study used thematic analysis to explore the child and adolescent abuse experiences and their impact on the pre-migration mental health of LGBT forced migrants. We analyzed 26 interviews with individuals who obtained refugee or asylee status in the United States or Canada on the basis of sexual orientation or gender identity. Participants originated from countries in Asia, Africa, the Caribbean, Eastern Europe, Latin America, and the Middle East. Analysis revealed the following themes: abuse by parents and caregivers, abuse by peers and school personnel, having nowhere to turn, and dealing with psychological distress. Findings indicate that participants experienced severe verbal, physical, and sexual abuse throughout childhood and adolescence and that this abuse occurred at home, in school, and in the community. Furthermore, there were no resources or sources of protection available to them. Participants linked their abuse to subjective experiences of depression, anxiety, and traumatic stress, as well as suicidal ideation and suicide attempts. We conclude with implications for refugee adjudication practices, mental health care, and international policy.

description: In this paper, some test procedures for scale parameters of exponential and rectangular
distributions involving the median ranked set sampling (MRSS) method are discussed.
The necessary tables for the critical regions for the suggested tests are supplied. The
power functions of the tests are compared with the power functions of the same tests
suggested by Abu-Dayyeh and Muttlak (1996) using ranked set sampling (RSS) data. It is
seen that the test procedures using the MRSS data have greater power than those using
the RSS data when the sample is drawn from an exponential distribution.

Surfing with Singer

description: I ran into Peter Singer recently ­– or at least we smiled at each other as our paths crossed in a beachside car park. Although we have friends in common, I didn’t stop to introduce myself. I was caught up in a conversation, but I also momentarily feared I might have mistaken him for somebody else: in a wetsuit, everyone looks a little bit different and a little bit the same. I know he surfs at that spot, though, so it almost certainly was Australia’s most famous philosopher checking the swell. My friend and I were returning from taking a look and had concluded that the waves were too small and messy. Perhaps we should have shared that information, but then we might have denied him a certain pleasure; a few minutes spent gazing at the ocean can never be counted as wasted time. Seeing Peter Singer at the beach reminded me of an event at Melbourne’s Wheeler Centre a couple of years ago. His presentation that day, and particularly his answer to a question from a woman named Rachel, has nagged at me ever since.
