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

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

Simulation and optimization model for the construction of electrical substations
No full textOne of the most complex construction projects is electrical substations. An electrical substation is an auxiliary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Construction of electrical substation includes civil works and electromechanical works. The scope of civil works includes construction of several buildings/components divided into parallel and overlapped working phases that require variety of resources and are generally quite costly and consume a considerable amount of time. Therefore, construction of substations faces complicated time-cost-resource optimization problems. On another hand, the construction industry is turning out to be progressively competitive throughout the years, whereby the need to persistently discover approaches to enhance construction performance. To address the previously stated afflictions, this dissertation makes the underlying strides and introduces a simulation and optimization model for the execution processes of civil works for an electrical substation based on database excel file for input data entry. The input data include bill of quantities, maximum available resources, production rates, unit cost of resources and indirect cost. The model is built on Anylogic software using discrete event simulation method. The model is divided into three zones working in parallel to each other. Each zone includes a group of buildings related to the same construction area. Each zone-model describes the execution process schedule for each building in the zone, the time consumed, percentage of utilization of equipment and manpower crews, amount of materials consumed and total direct and indirect cost. The model is then optimized to mainly minimize the project duration using parameter variation experiment and genetic algorithm java code implemented using Anylogic platform. The model used allocated resource parameters as decision variables and available resources as constraints. The model is verified on real case studies in Egypt and sensitivity analysis studies are incorporated. The model is also validated using a real case study and proves its efficiency by attaining a reduction in model time units between simulation and optimization experiments of 10.25% and reduction in total cost of 4.7%. Also, by comparing the optimization results by the actual data of the case study, the model attains a reduction in time and cost by 13.6% and 6.3% respectively. An analysis to determine the effect of each resource on reduction in cost is also presented
"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.

Simulation and optimization model for electrical substation construction
No full text© 2018 The author(s). One of the most complex construction projects is electrical substations. Construction of electrical substation includes civil works and electromechanical works. The scope of civil works includes construction of several buildings divided into parallel and overlapped working phases that require variety of resources and are generally quite costly and consume a considerable amount of time. The construction industry is becoming increasingly competitive over the years, whereby the need to continuously find ways to improve construction performance. In order to address the aforementioned adversities, this paper takes the initial steps and presents simulation and optimization model for the execution processes of civil works for an electrical substation using a data base excel file for input data entry. The input data include bill of quantities, resources breakdown, maximum available resources, production rates, unit cost of resources and indirect cost. The model is built on Anylogic software using discrete event simulation method. The model is divided into three zones working in parallel to each other. Each zone includes a group of buildings related to the same construction area. Each zone-model describes the execution process of each building in the zone, the time consumed, percentage of utilization of equipment and manpower crews, amount of materials consumed, total direct and indirect cost. The model is then optimized to mainly minimize the project duration using a parameter variation experiment and a genetic code implemented using Anylogic platform. The models were then tested on a real case study in Egypt. The models prove efficiency by attaining a reduction in model time units between simulation and optimization experiments of 10.25% and reduction in total cost of 4.7%. An analysis to determine the effect of each resource on reduction in cost was presented. However, the model is limited to the scope of civil works, without considering the electromechanical works and the effect of risk factors on time and cost
A unified framework to identify and extract uncertainty cues, holders, and scopes in one fell-swoop
No full textUncertainty refers to the language aspects that express hypotheses and speculations where propositions are held as (un)certain, (im)probable, or (im)possible. Automatic uncertainty analysis is crucial for several Natural Language Processing (NLP) applications that need to distinguish between factual (i.e. certain) and nonfactual (i.e. negated or uncertain) information. Typically, a comprehensive automatic uncertainty analyzer has three machine learning models for uncertainty detection, attribution, and scope extraction. To-date, and to the best of my knowledge, current research on uncertainty automatic analysis has only focused on uncertainty attribution and scope extraction, and has typically tackled each task with a different machine learning approach. Furthermore, current research on uncertainty automatic analysis has been restricted to specific languages, particularly English, and to specific linguistic genres, including biomedical and newswire texts, Wikipedia articles, and product reviews.
In this research project, I attempt to address the aforementioned limitations of current research on automatic uncertainty analysis. First, I develop a machine learning model for uncertainty attribution, the task typically neglected in automatic uncertainty analysis. Second, I propose a unified framework to identify and extract uncertainty cues, holders, and scopes in one-fell swoop by casting each task as a supervised token sequence labeling problem. Third, I choose to work on the Arabic language, in contrast to English, the most commonly studied language in the literature of automatic uncertainty analysis. Finally, I work on the understudied linguistic genre of tweets.
This research project results in a novel NLP tool, i.e., a comprehensive automatic uncertainty analyzer for Arabic tweets, with a practical impact on NLP applications that rely on uncertainty automatic analysis. The tool yields an F1 score of 0.759, averaged across its three machine learning models. Furthermore, through this research, the research community and I gain insights into (1) the challenges presented by Arabic as an agglutinative morphologically-rich language with a flexible word order, in contrast to English; (2) the challenges of the linguistic genre of tweets for uncertainty automatic analysis; and (3) the type of challenges that my proposed unified framework successfully addresses and boosts performance for.Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-05-01The student, Rania Al-Sabbagh, accepted the attached license on 2015-04-15 at 17:11.The student, Rania Al-Sabbagh, submitted this Dissertation for approval on 2015-04-15 at 18:45.This Dissertation was approved for publication on 2015-04-17 at 09:35.DSpace SAF Submission Ingestion Package generated from Vireo submission #7879 on 2015-07-22 at 14:17:56Made available in DSpace on 2015-07-22T22:33:25Z (GMT).

Den operativa självständigheten : En studie som berör förutsättningar för effektiv revision
No full textTitel: Den operativa självständigheten: En studie som berör revisorns förutsättningar att arbeta effektivt Nivå: C-uppsats i ämnet företagsekonomi Författare: Sara Eriksson och Rania Fannoun Handledare: Jan Svanberg Datum: 2016-01 Syfte: Klientens möjlighet att påverka revisorns effektivitet är sparsamt utforskad. Studiens syfte är att belysa vilka hinder som ligger i vägen för den operativa självständigheten samt vilka strategier revisorer använder sig av för att minimera påverkan. Metod: Studien bygger på en kvalitativ forskningsmetod. Datainsamlingen sker genom semistrukturerade intervjuer med fokus på subjektiva berättelser. Urvalet består av tiorespondenter, fem revisorer och fem redovisningsansvariga. Empirisk data spelas in, transkriberas, kodas utifrån teman och bearbetas. Resultat och slutsats: Den operativa självständigheten äventyras när klienten motsätter sig revisorns krav på information och material. Resultatet tyder på att vissa klienter lämnar material sent, eller i dåligt skick, samt placerar revisorn långt ifrån redovisningsmaterialet. Den operativa självständigheten påverkas även av kulturella skillnader samt när revisorn blir otrevligt bemött. För att minimera faktorernas påverkan används olika strategier. Studien visar vikten av att revisorn skapar en god relation, har hög social kompetens, kan förhandla samt är påläst inför revisionen. Förslag till fortsatt studie: Vi har sett ett behov av vidare studier kring risker som uppstår till följd av strategierna. Djupare studier skulle även kunna göras om konsekvenserna av att revisorn måste ta hänsyn till klientens vilja. Uppsatsens bidrag: Studien bidrar till revisionsbranschens tillsynsmyndighet och branschorganisation genom att belysa problematiken med klienters möjligheter att påverka revisorns effektivitet. Vilket kan öka deras intresse för omprövning av rekommendationer och institutionella åtgärder.Title: The operational independence: A study dealing with auditors’ ability to work effectively Level: Final assignment for Bachelor Degree in Business Administration Author: Sara Eriksson and Rania Fannoun Supervisor: Jan Svanberg Date: 2016-01 Aim: Client's ability to influence auditors efficiency is not enough explored. The study seeks to highlight impacts on operational independence and different strategies to minimize those impacts. Method: Qualitative research. Data is collected through semi-structured interviews with focus on subjective stories. The sample consists of ten respondents, five auditors and five clients. Empirical data are recorded, transcribed, coded based on themes and processed. Result & Conclusions: The operational independence is compromised when clients oppose auditors’ demands on required information. The result shows that some clients are late in delivering, or deliver data in bad condition. The operational independence is also influenced by cultural differences, and when the auditor is responded unpleasantly. To minimize the impact of these factors, auditors use different strategies. The study shows that it is important that auditors create a good relationship with clients, have a high social competence, negotiation skills and are prepared before the audit process. Suggestions for future research: We’ve seen a need for further studies on the risks that arise as a result of the strategies. Deeper studies could also be made about the consequences due to the consideration that the auditor must take into the client’s will. Contribution of the essay: The study contributes to audit regulation and audit association by highlighting problems with clients’ ability to influence auditors’ efficiency. This may increase their interest in revised recommendations and institutional action. Keywords: Auditor, operational independence, competence, independence, working atmosphere, auditor-client
