Unbalanced bidding is a common practice used in both unit price and lump sum contracts. Contractors may unbalance their bids in different forms for various reasons. The studies in the literature either focus on developing optimization models that assist contractors in winning contracts and maximizing profits of their bids through unbalancing or developing models that assist owners in detecting and/or preventing unbalanced bids during the bid evaluation stage. Unbalanced bidding is one of the most controversial subjects in the construction management literature and practice. Although there is no consensus on whether it is unethical or not, this practice is not usually for the benefit of owners. Therefore, owners have the right to reject the unbalanced bids and create a fair competition environment if they have a mechanism to detect it during the bid evaluation process. The main objective of this study is to propose a model, which consists of five different grading systems and helps owners in detecting unbalanced bids during the tendering process. In the proposed model, owners may either calculate the individual grades of each bidder or calculate the final score of each bidder by assigning different weights to these grading systems according to the project characteristics or their own needs. The final scores and bid prices of the contractors can be simultaneously evaluated. In order to demonstrate the applicability of the proposed model, an illustrative example is presented. It can be concluded that the proposed model can be effectively and easily used by owners for detecting unbalanced bids. This paper is the revised version of the paper that has been published in the proceedings of the Creative Construction Conference 2018 (Polat et al., 2018).

One success factor of an online affiliate is determined by the quality of the content source. Therefore, affiliate marketplaces need to do an objective assessment to retrieve content data that will be used to choose the right product in the appropriate product filter. Usually, the selection is not made using a good and measured system so that the selection of product content is only based on parts that are not in accordance with what is seen or subjective. However, if analyzed using a good and measurable system will produce an objective product content and can have a positive impact on users because the selection is based on factual data. The purpose of this research is to analyze the potential of the affiliate marketplace by combining cosine similarity with vision-based page segmentation. This is a new breakthrough made for optimization to get the best content in accordance with the required criteria. This work will produce a number of product recommendations that are appropriate for publication and then made use of for comparison that matches the required criteria. At the limited evaluation stage, the performance of the proposed model obtained satisfactory results, in which 5 queries tested were all as expected.

Sanitation Infrastructure

The Analytic Network Process (ANP) approach was applied to evaluate the overall project performance. The interdependencies between the performance factors in sanitation infrastructure projects have been modeled, and their cumulative influences were simulated and quantified. This model focuses on the planning and construction phase of projects under unit price contracts and is intended for use by owners, supervision consulting firms (Owner’s representative) and/or contractors as well. The proposed model assist both owners, consultants and contractors in controlling projects during the different phases and can also be used as a basis for simulation of various managerial scenarios/interventions to explore the best solution to correct the negative effect of poor performance. The proposed model is generic and may be applicable to almost any project in the construction industry, since all projects, regardless of size or type, follow a broadly similar pattern of development. This model focuses on the two phases; planning phase and construction phase of a project and is intended for implementation by both owners and contractors. Although the proposed evaluation model reflects to a great extent the contractors’ preferences, most contractors perceive performance according to project objectives and contractual aspects. The model also reflects to some extent the owner’s and/or its consultant’s interventions within the different project cycle. Therefore, the objective of this research is not to standardize the priorities of performance factors, but rather to establish a systematic framework for consistent and quantitative evaluation process for performance of planning and construction of sanitation infrastructure projects in Egypt that take into consideration the interdependencies between multidimensional performance factors.

Reflective Skills

This article outlined a model for guidance in ‘doing’ bioethics in a Reformed context. The proposed model suggested that in order to arrive at responsible ethical decisions, one must refer to both contextual elements and theory. The theoretical grounding for this model was based on the integration of a deontological and virtue ethics approach, arguing that virtue enables persons to know and desire the right moral ends and motivates them to carry out appropriate action toward achieving these ends. An integrative model opens up the possibility whereby bioethics as a systematic tool provides the individual decision-maker with the critical-reflective skills and justification for the ultimate choice that is lacking in the general decision-making processes. This could lead to clearer thinking and increased confidence in the justification of decisions within the Reformed tradition. The proposed hermeneutical perspective on ethical decision-making represents a shift in views about the nature of knowledge and the process of how we come to know. The key to this hermeneutical approach is to acknowledge the dialectic between the universal and the subjectivity of human relations. Working in specific religious communities, one needs to take cognisance of the fact that knowledge is situated in the context of human relationships in which the interpreter participates when articulating the meaning of bioethical experiences. Another aspect that is anticipated lies in the realisation that people struggling with bioethical dilemmas should not be viewed as isolated individuals, but as members of a broader faith community.‘n Geïntegreerde etiese benadering tot bioetiese besluitneming: Voorgestelde model vir predikante. Hierdie artikel het ‘n model geskets wat moontlike riglyne aantoon vir die  beoefening  van  bioetiek  binne  ‘n  Gereformeerde  konteks.  Die  voorgestelde  model argumenteer dat verwysing na beide kontekstuele elemente en teorie onafwendbaar is om tot verantwoordelike bioetiese besluite te kan kom. Die teoretiese begronding vir hierdie model het op die integrasie van deontologiese- en karakteretiek berus en is gebaseer op die argument dat karakteretiek persone in staat stel om die regte morele doelwitte te ken en motiveer hulle ook om die nodige stappe te neem om dit te bereik. ‘n Geïntegreerde model skep die moontlikheid vir bioetiek as ‘n sistematiese stuk gereedskap om die individuele besluitnemer met die kritiesreflektiewe vaardighede en gronde vir regverdiging van die finale keuses toe te rus, aspekte wat in algemene besluitnemingsprosesse ontbreek. Dit kan ook lei tot helderder denke en groter vertroue in die motivering van besluite binne die Gereformeerde tradisie. Die voorgestelde hermeneutiese perspektief op etiese besluitneming verteenwoordig ‘n verskuiwing in aanvaarde sienings oor die aard van kennis en die prosesse wat tot kennis lei. Die sleutel tot hierdie hermeneutiese benadering is om erkenning te gee aan die dialektiek tussen die universele en subjektiewe menslike verhoudings. Dit is veronderstel dat persone wat in spesifieke geloofsgemeenskappe werk daarop ag moet slaan dat kennis binne die konteks van menslike verhoudings – waarbinne die interpreteerder funksioneer – gesetel is wanneer die betekenis van bioetiese ervaring geartikuleer word. ‘n Verdere aspek was die erkenning van die feit dat mense wat met bioetiese dilemmas worstel nie as geïsoleerde individue beskou moet word nie, maar as lede van ‘n breër geloofsgemeenskap.

Abstract The latest mobile technology options have heightened the interest in AAC today. Due to the ease of access and the availability of this technology, there are considerably more device choices available for persons with complex communication needs (CCN). There is an opportunity to build upon the enthusiasm surrounding these new mobile technologies by including all stakeholders in the AAC evaluation process. The clinician needs to ensure the use of sound AAC evaluation principles and procedures and prioritize the individual needs of the communicator. Recommendations about the use of an AAC high-tech device should flow from the evaluation and feature-matching process. The purpose of this paper is to suggest new ways to revisit the basics of a comprehensive AAC evaluation in order to better ensure that individuals who use AAC are being provided with the tools and features they need.

Italian Constitution

Art. 24 of the 1948 Declaration of Human Rights recognises and protects the right of the individual to rest and leisure. This right has to be fully exercised without negative consequences on the right to work and the remuneration. Tourism can be considered one of the best ways of rest and leisure because it allows to enrich the personality of the individual. Even after the reform of the Title V this area is no longer covered by the Italian Constitution, the Italian legal system protects and guarantees it as a real right, so as to get to recognize its existence and the consequent compensation of the so-called “ruined holiday damage”. This kind of damage has not a patrimonial nature, but a moral one, and the Tourist-Traveler can claim for it when he has not been able to fully enjoy his holiday - the essential fulcrum of tourism - intended as an opportunity for leisure and/or rest, essential rights of the individual.

Values are like seeds that sprout, become saplings, grow into trees and spread their branches all around. To be able to think right, to feel the right kind of emotions and to act in the desirable manner are the prime phases of personality development. Building up of values system starts with the individual, moves on to the family and community, reorienting systems, structures and institutions, spreading throughout the land and ultimately embracing the planet as a whole. The culture of inclusivity is particularly relevant and important in the context of our society, nation and making education a right for all children.

The current world situation is both frightening and alarming due to the massive disruption caused by the Covid-19 pandemic. The next few days are censorious as we need to be very precautious in our daily regimen as well as dietary habits. Ayurveda offers knowledge about food based on certain reasoning. Indecent food custom is the chief cause for the rising development of health disorders in the current era. In classical texts of Ayurveda, the concept of diet explained well, ranging from their natural sources, properties and specific utility in pathological as well as physiological manner. In this work, the review of the relevant literature of Ahara (Diet) was carried out from Charak Samhita and other texts, newspapers, articles, web page related to the same.  Every human being is unique with respect to his Prakriti (Physical and mental temperament), Agni (Digestive capacity), Koshtha  (Nature of bowel) etc. For that reason, the specificity of the individual should be kept in mind. Ahara, when consumed in the appropriate amount at the right moment following all Niyamas (Guidelines) given in Ayurveda texts, gives immunity and keeps the body in a healthy state during pandemics such as Covid-19. Ultimately, this will help the human body to maintain its strength for life. This article reviews the concept of diet viz. combination of foods, their quantity and quality, methods of preparation and processing, which are to be followed during pandemics and are essential in maintenance and endorsement of health and preclusion of diseases.

Despite South Africa’s celebrated constitutional commitments that have expanded and deepened South Africa’s commitment to realise socio-economic rights, limited progress in implementing right to food policies stands to compromise the country’s developmental path. If not a deliberate policy choice, the persistence of hunger, food insecurity and malnutrition in all its forms is a deep policy failure.  Food system transformation in South Africa requires addressing wider issues of who controls the food supply, thus influencing the food chain and the food choices of the individual and communities. This paper examines three global rights-based paradigms – ‘food justice’, ‘food security’ and ‘food sovereignty’ – that inform activism on the right to food globally and their relevance to food system change in South Africa; for both fulfilling the right to food and addressing all forms of malnutrition. We conclude that the emerging concept of food sovereignty has important yet largely unexplored possibilities for democratically managing food systems for better health outcomes.
