Studying Migration from Different Perspectives and with Different Techniques
No full textMigration can be considered a human strategy to improve life and can be defined as a natural behavior of human beings that has developed over time. The issue of migration is a particularly salient theme in this historical period and presents a new challenge for researchers in Europe and worldwide, particularly those researchers attempting to understand the patterns and processes of migration. Researchers of various disciplines have responded to the challenges related to migration using a variety of methodological tools to examine the phenomenon. In this chapter, the author presents qualitative techniques used in the social sciences and discusses their strengths and weaknesses when they are employed to study immigrant populations. Given the complexity of the migration phenomenon, the challenges that researchers must address include collaboration between disciplines and methodologies and the integration of methods. A multimethod, multilevel and multidisciplinary approach is used in an attempt to understand this multifaceted issue

Protein as the building blocks of life / Rania Farzana Azmi ... [et al.]
No full textProtein is not limited to being a source of food but also provides other benefits such as maintaining body weight, key nutrients for bone health and reduces disease risks including type 2 diabetes and neurodegenerative diseases such as Alzheimer’s, Huntington’s and Parkinson’s disease. With those benefits, it is essential to consume protein for optimal growth and development in an individual. Proteins are made up of amino acids and can be classified into four major structures. Primary structure is a linear sequence of amino acids in a polypeptide chain with an example of insulin productions. Next, protein secondary structure includes alpha-helix or folded into beta-pleated sheets due to their crucial structure role in most globular and fibrous proteins. The formation of alpha-chain and betapleated sheets is due to hydrogen bonding between carbonyl and amino groups in the peptide backbone. Moving on to the production of essential biological compounds such as enzymes, hormones, antibodies, and plasma protein which are the examples of tertiary structure that either has folded helix or formed pleated sheet into a 3-D polypeptide shape. Factors influencing the R chain in tertiary structures include ionic interactions, hydrogen bonds, Van der Waals depressive forces, and sulfur
bridges mainly caused by amino acid group interactions. Quaternary structure is the combination of two or more tertiary structure polypeptide chains that form one large and complex protein molecule. For instance, the synthesis of haemoglobin where the organisation of protein is in multiple subunits. Evidence from repairing and building new cells in providing one’s body framework proves that proteins must be included in our daily diet to maintain a healthy lifestyle
Psicologia sociale delle relazioni familiari .Identità, progetti e traiettorie
No full textFamily, in a psycho-social perspective, can be considered challenged in epistemic sense: by its nature it is compared with the contexts of change, with the ability to adapt to life events that are varied and numerous. The family may be regarded as a "project" that turns to unify different situations, sometimes contradictory, going to define family "paths" increasingly differentiated and difficult to predict. These pathways may be dependent on life events not selected that people suffer all the consequences, or from events strongly desired that bring people to possible happiness or unhappiness.
The author outlines a scenario that includes the varied strategies of coexistence in which family meanings can be very different; along with a “liquid” love and society, the family no longer seems able to hold its form. The construction of its boundaries and relevant meanings, through the current multiplicity of family forms which each of us can experience simultaneously, is the main challenge relates to the ability of each to build and maintain links
"Promoting Gender Equality through Stimulus Packages and Public Job Creation: Lessons Learned from South Africa’s Expanded Public Works Programme"
No full textBeyond loss of income, joblessness is associated with greater poverty, marginalization, and social exclusion; the current global crisis is clearly not helping. In this new Public Policy Brief, Research Scholar Rania Antonopoulos explores the impact of both joblessness and employment expansion on poverty, paying particular attention to the gender aspects of poverty and poverty-reducing public employment schemes targeting poor women. The author presents the results of a Levy Institute study that examines the macroeconomic consequences of scaling up South Africa's Expanded Public Works Programme by adding to it a new sector for social service delivery in health and education. She notes that gaps in such services for households that cannot afford to pay for them are mostly filled by long hours of invisible, unpaid work performed by women and children. Her proposed employment creation program addresses several policy objectives: income and job generation, provisioning of communities' unmet needs, skill enhancement for a new cadre of workers, and promotion of gender equality by addressing the overtaxed time of women.
