    How Food consumption is treated for discriminating people?

    eating some type of food is considered to deem people superior and some other food eating is treated inferior ... what are reasons 

    Sean Walker

    This has become a very interesting point of discussion in the United States. In particular, there is a lo of discussion on the ability of lower income households to have access to healthier foods. This lack of access leads to poorer health. This then leads to higher healthcare costs of these individuals.

    In general, there seems to be many misconceptions that stem from this.

  • David Pérez Jorge added an answer:
    Why do you think that children discriminate against children with disabilities?

    My experience leads me to believe that the values of respect are learned but not really taught how to treat people with disabilities.

    Inclusion in schools is not real if it is not taught to relate well to children with disabilities
    The lack of skills and lack of positive experiences is a reality. Avoid contact children not to fail in their relationship

    David Pérez Jorge

    Dear George and Beata

    This is hard work but you have to keep making people more sensitive to the reality of children with disability. The laws do not change consciences, for those teachers have to be the protagonists of this change of mentality. Inclusion is more than integration and we must fight for it.
    Best reguards.

    Which stimuli could be used for a German IAT about Sinti and Roma?

    I am searching for stimuli that can be used in an implicit association test (IAT) to measure associations with Sinti and Roma.

    Existing research used surnames or photographs, which would not be practicable or useful in Germany, as typical Roma surnames do not exist here and photographs of Roma people wouldn’t be recognizable without using stereotypes again.

    Does anyone have an idea which stimuli (apart from "Sinti", "Roma" and "Sinti and Roma") could be used for the target category?

    Thank you in advance!

    Christine Ebbeler

    Dear all,

    Thanks a lot for your comments and for taking time to think about this problem.
    I think we are going to present participants some (non-stereotypical) words prior to the IAT (i.e. "Romanes is the name of the language most Roma speak", "Romni is the female singular of the word Roma" etc) and then use these words as stimuli in a single-target IAT.
    Thank you for your help!

    Does anyone knows about ageism and inequality?

    I am just starting a research project on this topic (more concretely: ageism and inequality in Ecuador). While I do have some idea on each one of the topics, I have a hard time to bring them together - does anyone of you know about studies on ageism and inequality, maybe with a policy perspective?

    Anitra Nelson

    I agree Phillip, a cross-cultural cross-country comparison would be really useful. National policy, opportunity, health and expectations are key areas that especially deserve comparison. Pensions, superannuation and aging in place welfare policies are important policy and opportunity contexts for over 60 year olds. I also think that the gender aspect is really interesting. Women over 60 years of age in Australia are less financially well off than men yet likely to live longer. We're seeing greater numbers of homeless women in this age range.

  • Artur Braun added an answer:
    What is the difference between discrimination and prejudice?

    Can you help me understand better the different antecedents and implications of the differences between discrimination and prejudice? Are they independent or interdependent? How would do you address their overlap statistically?

    Artur Braun

    Discrimination is when you treat people of different groups different by intention although these people should rank equal. If you deny equal treatment where equal treatment is due. I would say this constitutes discrimination. It does not happen because of ignorance and not because of prejudice.

    Prejudice is when you base your judgement on a readily available personal data set about people. Such as racial profiling. As a border control officer in a northern Europe country, you stop the dark sink traveller rather than the white skin traveller because chances are that the dark skin traveller needs additional documentation for travelling (visa) and may fail so to have with more probability than a a white skin person who would need no visa. This behaviour is an extrapolation from statistics experience (which however may be self reproductive).

    The prejudice may be a simple judgemental mistake, whereas the discrimination is an intentional mistreatment where equality is due. Such as giving female workers a lower salary than male workers despite equal performance. Or giving immigrant workers worse jobs then own nationals despite higher qualification or better merits of the former.

  • Debra Sharon Ferdinand added an answer:
    Is anyone aware of studies on the affect diversity mandates have on teacher candidates?

    NCATE and most teacher preparation institutions include "diversity" as a necessary component of pre-service training.  But in looking at how these are implemented - through casual conversations, hence the request for reserach :) - these tend to simply teach about cultural differences.

    In other words, they seem to define "Native Americans", "LGBT Americans", "African Americans" and other minorities by their skin color or sexual orientation and recommend strategies for dealing with this.  

    My interest is if these promote positive affects on student learning or if they create a negative externality where teacher candidates engage in implicit racism (such as: I have a Native student so I need to use cooperative learning for him, e.g. - defining him by his race)

    Debra Sharon Ferdinand

    From research in the U.S., I think the diversity mandates may be missing the mark. In one study, it was revealed that the "majority" seldom attend the diversity training workshops on campus, so they are not able to really impact the diversity in the classroom (online and F2F):

      ABSTRACT: Growing ethnic student diversity (to include Caribbean students) on U.S campuses requires exercising cultural sensitivity in classroom teaching, in accommodating for the culturally/internationally diverse students in U.S. classrooms. A Midwestern university embarked on a diversity thrust that included workshops for boosting faculty cultural competence in facilitating culturally/internationally diverse learners. This descriptive study examined the extent to which cultural insensitivity existed in WED teaching delivery. A With-in Stage Mixed Model research design and a pragmatic paradigm were employed to guide the study’s design and data collection/analysis of its census survey data consisting of quantitative and qualitative data from three student groups: Minority, Majority, and International. Findings included the following: International students felt that cultural insensitivity occurred in verbal and non-verbal communication with students in WED teaching delivery very often; U.S. majority and minority students felt it almost never or sometimes occurred respectively. Suggestions from WED graduate students for addressing this cultural deficit mainly include faculty diversity training and diversification of teaching styles, in keeping with multicultural education, ethnocentrism and critical race theory.

    How does racism within US popular culture impact black males in the US?

    I am looking for journal articles that would help assist me in answering that particular research question.

    Alex Colvin

    I think part of the answer is in anthropology and how humans embrace "folk taxonomies" with regard to race (which has no biological basis,) and part in history when we look at the American slave tradition. It's also important to remember that not all Native Americans were destroyed or sent to reservations. One has but to look at the Seminole in Florida  and their history to see how they triumphed over Jacksonian extermination policies. Seminole, is actually a Creek name; the Seminole were not a tribe unto themselves, but a band of renegade Creek who left and went into Spanish Florida where they were allowed to settle. The Creek name for them was "seminole" which meant runaways. I.E. they fled their tribe.  As whites pursued them hoping to open up the territory to white settlers,  the Seminole engaged in guerilla warfare and eventually migrated into the Everglades where the whites could not navigate at the time. They are one of the few indigenous people never uprooted nor who ever truly assimilated.  Their warfare with the U.S. military lasted until 1958 -- easily the longest running war within the U.S. between NAs and the U.S. military on U.S. soil. The U.S. eventually just gave up.

    There is a global trend towards an aging population. In this context it is questionable whether the age limit in employment could be a discriminatory criteria.

    Personally I have seen ageism as a swept under the carpet reality. Sure it is against the law but very little is done to stop this widespread practice against older persons actively pursuing employment. There are certain areas where older workers are common, WalMart for example but tactful anti older worker hiring practices are well entrenched norms.

  • Paul Louangrath added an answer:
    What is the best method to validate a questionnaire based on a 5 point Likert scale?

    I want to check internal consistency, face validity, content validity, convergent and discriminant validity of a questionnaire. What are the latest and best methods for determining these?   

    Paul Louangrath

    ISSUE: Validity Tests

    VALIDITY: Validity is defined as the degree of agreement between the claimed measurement and the real world. There are three categories of validity test, namely: (i) content validity, (ii) criterion validity, and (iii) construct validity. Content validity seeks to answer the question of whether the current test covers all relevant items needed to answer the research question. Criterion validity is the degree of correlation between the current test to the predetermined standard. The predetermined standard scores are those that had been tested by prior studies and had been held to be valid. Construct validity is the degree to which the test actually measures what the theory claims.

    (i) Face Validity. Use the respondents to answer the question: Does the survey or test measure what it intended to measure? This is the subjective view of the respondents to the survey (not experts). Use this as a test-run before distributed the real survey.

    (ii) Content Validity. Use expert panel to answer the question: Is the question or skills measurement int he test "essential" to the intended measurement? Form a panel of subject mater experts (SME) and then ask them whether your intended questions or survey is relevant to your intended research issue? Use the Lawshe test:

    CVR = [(ne - N)-N/2 ] / 2

    ... where CVR = content validitt ratio' ne = number of experts in the panel answered "yes, relevant"; and N = total number of experts in the panel.

    (iii) Construct Validity. There are two kinds of construct validity: (a) convergent validity and (b) discriminant validity. A convergent construct validity exists when what is expected to be correlated indeed turns out to be correlated, thus H0: r = 0 and HA: r not equal to 0. The result shows that H0 is incorrect and, thus, is rejected. Whereas, in discriminant validity, r = 0; H0 cannot be rejected. Use correlation coefficient as the unit of analysis.

    INTERNAL CONSISTENCY: It appears that the Cronabach's alpha is a common test. However, Cronbach himself had recently admitted that the Cronbach’s alpha is not an appropriate test for reliability. Cronbach wrote that:

    “I no longer regard the alpha formula as the most appropriate way to examine most data. Over the years, my associate and I developed the complex generalizability (G) theory. (Cronbach et al. (1963); Cronbach et. al. (1973); see also Brennan (2001); Shavelson and Webb (1991), which can be simplified to deal specifically with a simple two way matrix and produce coefficient alpha (Cronbach (2004), p. 403). Cited in N.M. Webb, R.J. Shavelson and E.H. Haertel (2006). “Reliability Coefficients and Generalizibility Theory.” Handbook of Statistics, Vol. 26, p. 2. ISSN 0169-7161.

    Therefore, the use of Cronbach’s alpha must be reexamined. This is not to say that Cronbach’s alpha is not usable; its use and interpretation, however, must be modified. It is a tool to determine whether the response is consistent; this is different from asking whether the instrument produces consistent response?.

    Does anyone know of any recent research on the association between children's involvement in musical activities and their communication development?

    Research has shown that a developing foetus can discriminate sounds in the womb from 22 weeks gestation and that early sound discrimination helps to promote later phonic and vocabulary development. In addition, during early social interaction between caregivers and infants there are noticeable patterns of timing, pulse, voice timbre, and gesture that follow many of the rules of musical performance, including rhythm and timing conceptualised by Malloch and Trevarthen (2009) as ‘communicative musicality’. Given the centrality of communication in children’s learning and development (Blackburn, 2014) and the established links between human communication and music, this project seeks to explore the views, understanding and reported practices of interested stakeholders in young children’s musical interactions in home and out-of-home early years settings.Does anyone know of any research that might help with a project and guide the literature review?

    Jolanthe de Tempe

    Hi Carolyn,

    No, the article by Deru & Verhofstadt hasn't been translated. But it it is mainly a summary of the studies by Van Puyvelde c.s., which is in English. In the study of musical synchonization between mothers and infants they link musical synchonisation (in pitch as well as in rythm)  between mothers and babies to mutual attunement and intersubjectivity, which is known to be important for the babies' secure attachment, which in turn is important for their development and mental health in many aspects, also later in life (e.g. Daniel Hughes, Attachment-focused family therapy, 2007, and Mikulincer & Shaver's review of resarch in Attachment and adulthood, 2007).

    Precedence Case: Language requirements for EU-students studying in other Member States - high or low?
    In many member states of the EU (and specifically in Germany) each University is able to set its own standards of language requirements (some recommendations exist from the HRK, but neither regulation nor law).
    Generally speaking a university can follow two tracks for education:
    1) 'Elitism' and trying to attract the best (for professors, students, research, ...) which (can) lead to effect that entry language criteria are very high so no language student support has to be given or hinders academic understanding
    2) 'Place of Learning' meaning that in a mobile EU for most languages students which not have acquired a academic level of the language and students must be given the chance to enter other Member States with medium language levels and continue learning the language at the host university/state

    The highest administrative court in Bavaria has now recognized the discrepancy between European standards and unusually high demands of universities and in the Case of Fuentes given protection (http://www.discrimination.guru/?p=52)

    What do you think?

    PS: for mobile workers (doctors, lawyers, pharmacists, ...) it is already decided. Language levels must be uniform and low to avoid discrimination

      ABSTRACT: In Germany, higher education depends on the Länder themselves. Each Land decided herself, what language requirements she demands from students before taking up their studies at university if they do not hold German nationality. Usually in the provincial laws an adequate knowledge is described as a requirement and it is left to universities to decide for which degree they require which specific level of German. Usually universities require levels ranging from B2-C2 under the Common European Framework of Reference for Languages This causes the following curiosities: ◾for different degrees, different levels of German are required ◾for the same degrees at different universities, different levels of German are required ◾from students holding German nationality but not speaking German (e.g. nationality received from parents but born and living in Latin America), no language certificate is required ◾from students having obtained the German nationality via naturalization, no language certificate is required although for naturalization in Germany only a B1 is needed In the case 7 CE 13.2222 the Bayerischer Verwaltungsgerichtshof (highest administrative court of Bavaria) confirmed that such an approach can constitute an infringement of European Law and asked the Verwaltungsgericht Ansbach (administrative court of Bavaria) to refer the case to the European Court of Justice for clarification. The student in question was given the right to access university meanwhile. The court wants to have clarified if levels demanded above B1 (prerequisite for naturalization) are then considered as discrimination.

  • Ella Pavlotskaya added an answer:
    Are minimal pairs and auditory discrimination grouped within phonological awareness?

    I want to know if I can group minimal pairs and auditory discrimination in phonological awareness category or these three are totally different?

    Ella Pavlotskaya

    My understanding of phonological awareness is the ability to correctly link phonemes to graphemes, as in reading acquisition. A child is aware, for example, that the letter x signifies the sound combination /ks/.  This is why words like "xylophone" to illustrate the concept are confusing, and some modern dyslexia remediating methodologies use words like "fox" instead.   Minimal pairs are sounds that are different from each other in voicing, whereas the same in placement (e.g., /b/ and /p/ are both bilabial sounds, but one of them is produced with vocal fold vibration and the other is a silent burst of air; similarly, /g/ and /k/ are both velar sounds, but one is voiced and the other is voiceless).  Auditory discrimination is a very early on process.  I believe babies acquire this skill by 6 months of age.  If your question is whether phonological awareness may be used as an "umbrella term" for both auditory discrimination and minimal pairs, I would say probably not.  To my understanding, phonological awareness is a metalinguistic skill, learned much later in development, than auditory discrimination, which is a developmental process. However, when there is a breakdown, and a child lacks the auditory discrimination skills and is unable to hear (and/or produce) sounds correctly, he/she requires remediation, where awareness of the difference between the sounds is explicitly taught via minimal pairs, often before the child is even able to read.  I hope this was helpful.

    A model of children's thoughts and feelings about groups of other children, intended and observed behaviours towards others would be useful in this situation.  Add foundations of children's thoughts about others - particularly identities (a sense of individuality, sense of belonging socially, identity of place - local, regional, national - and other identities).  This model is useful in monitoring attitudes towards other groups of children and suggests self-categorization theory as a basis for intervention programmes. 

    For instance, identities are included in the ASK-KIDS Inventory from ACER.

  • Rolando Garcia added an answer:
    How do you explain higher discrimination using a SVM score index (unsupervised) from a supervised SVM model using same dataset?

    By higher discrimination, we mean higher AUC and specificity.  The supervised SVM was trained, tested with a 10 fold cross validation.  In my opinion, I would tend to go with the lower results obtained from the supervised SVM - What is your take?

    Rolando Garcia

    James, No form of validation was used for the unsupervised SVM.  The independent test set is a great idea - however, data is limited.  And yes, there is probably difference in complexity - supervised model was validated by 10 CV and bootstrapping.

    I am looking for a self-report measure of perceived racial discrimination with good reliability & validity. Publicly available would be ideal. Any suggestions would be very much appreciated.

    Roger Keller Celeste

    Dear Eli,

    We have conducted a systematic review of scales, (published in Social Science and Medicine) but we found that none were appropriate for our purposed. Then, my colleague, Dr Bastos, developed one (published in Revista de Saúde Pública, link below). We are still improving it. I guess it will be helpful to you. It was planed for interpersonal discrimination from explicit demonstrations that individuals may observe when they are victims.

    It is a challenging construct to measure with many details. Even so, the scale has good psychometric properties and good validity among university students.

    Good luck.

      ABSTRACT: The literature addressing the use of the race variable to study causes of racial inequities in health is characterized by a dense discussion on the pitfalls in interpreting statistical associations as causal relationships. In contrast, fewer studies have addressed the use of racial discrimination scales to estimate discrimination effects on health, and none of them provided a thorough assessment of the scales' psychometric properties. Our aim was to systematically review self-reported racial discrimination scales to describe their development processes and to provide a synthesis of their psychometric properties. A computer-based search in PubMed, LILACS, PsycInfo, Scielo, Scopus and Web of Science was conducted without any type of restriction, using search queries containing free and controlled vocabulary. After initially identifying 3060 references, 24 scales were included in the review. Despite the fact that discrimination stands as topic of international relevance, 23 (96%) scales were developed within the United States. Most studies (67%, N = 16) were published in the last 12 years, documenting initial attempts at scale development, with a dearth of investigations on scale refinements or cross-cultural adaptations. Psychometric properties were acceptable; sixteen of all scales presented reliability scores above 0.7, 19 out of 20 instruments confirmed at least 75% of all previously stated hypotheses regarding the constructs under consideration, and conceptual dimensional structure was supported by means of any type of factor analysis in 17 of 21 scales. However, independent researchers, apart from the original scale developers, have rarely examined such scales. The use of racial terminology and how it may influence self-reported experiences of discrimination has not yet been thoroughly examined. The need to consider other types of unfair treatment as concurrently important health-damaging exposures, and the idea of a universal instrument which would permit cross-cultural adaptations, should be discussed among researchers in this emerging field of inquiry.

    Could you give me some explanations about Construct Validity" , "Discriminant Validity", "Composite Reliability" and "Convergent Validity"?

    Also could you tell me whether the below sentence is correct for "Convergent Validity" or no?

    "In spite of AVE for some variables are less than 0.5, the factor loadings are more than 0.5. Since all FL for the constructs are significant as required for convergent validity and their values are more than 0.5 then they are valid for convergent validity."

    Amipara Manilal D

    Construct validity means the parameter's defined/promised value is valid (does not go out of specified value) in normal condition. Discriminant validity means in a special case/s it has limitatiuon/s to have parameters value within specified limit. Composite reliability means failure of system depend upon multiple reasons and reliability calculated based on consideration of those multiple failures is called composite reliability.

    Can anyone help with the data selection for training an intrusion detection system?

    I have a dataset of network connections (KYOTO +2006) that each connection has a label of attack or normal. (It doesn't determine which kind of attack).

    According to a paper that I want to simulate, I need to choose RANDOMLY and FAIRLY a set of data which contain 1 percent of attack and 99 percent of normal but they did not discuss what does FAIRLY means.

    I discriminated data in to attack and normal and randomly choose 1% from attack and 99% from normal but my result was too different from the base paper and I think the problem is in Data selection?

    I have a question, Is data selection important in training an IDS (intrusion detection system) and what should I choose training data to be sure it covers all kind of attack and normal data.

    Maheyzah Md Siraj

    Dear Roya..

    I am not sure whether my answer is the one you search for.

    From my understanding, you already has labelled dataset (Attack or Normal). You must count the percentage of instances that have been labelled as Attack and Normal. For example if your dataset has 100 instances, and you need 1% attack and 99% of normal; then you should have only 1 instance labelled as attack and the rest are labelled as normal. So these 100 instances is your training dataset.

    You should have another set of dataset that will be used for testing. Preferably, testing dataset is not labelled. It can be old dataset or new dataset. The detection results (accuracy) from your testing dataset shows your detection performance/capability.

About Discrimination

An interdisciplinary group on discrimination. Contributing fields include but are not limited to (labor) economics, psychology, social psychology, and sociology. Definitions of discrimination differ between and within these fields. Usually, definitions of discrimination involve some sort of interpersonal treatment that is based on group membership rather than on individual characteristics. Usually, we study forms of discrimination that are considered unfair in a certain context (e.g. discriminating on the basis of race is considered unfair in education). This group is the place to discuss every question related to discrimination, such as: Which forms of discrimination should we distinguish? Which theories help us understand discriminatory behavior? Which methods are suited for studying discrimination? How to interpret particular findings?
