Role of food safety in procedures adopted for the purchase of minimally processed and fresh vegetables by foodservices

This research was designed to analyze whether the procedures adopted by foodservice establishments for the purchase of minimally processed and fresh vegetables favor the acquisition of safe products. This research investigated the purchasing policies of such establishments, whether self-managed or administered by foodservice contractors, in the municipality of Campinas and its outlying districts. A random sample of thirty-nine establishments participated in the research. The instruments for data collection were pre-tested, and the actual interviews were conducted by trained personnel. Comparative analyses were made using various statistical tests. All of the participating establishments purchase fresh vegetables, although only six of them use minimally processed ones. For most of the establishments, price is at least one of the most important criteria for the selection of a supplier, and they do not normally monitor the safety of the fresh products purchased (51.3%), nor do they make regular technical visits to guarantee quality (46.2%); moreover, most do not carry out a supplier development program. It is suggested that routine technical visits to suppliers should be adopted, as well as the creation of courses, such as those dealing with the safety of vegetables and supplier development, to be offered to foodservices.

Analysis of Phase Separator Design Criteria Using Computational Fluid Dynamics

Gravitational phase separation is a common unit operation found in most large-scale chemical processes. The need for phase separation can arise e.g. from product purification or protection of downstream equipment. In gravitational phase separation, the phases separate without the application of an external force. This is achieved in vessels where the flow velocity is lowered substantially compared to pipe flow. If the velocity is low enough, the denser phase settles towards the bottom of the vessel while the lighter phase rises. To find optimal configurations for gravitational phase separator vessels, several different geometrical and internal design features were evaluated based on simulations using OpenFOAM computational fluid dynamics (CFD) software. The studied features included inlet distributors, vessel dimensions, demister configurations and gas phase outlet configurations. Simulations were conducted as single phase steady state calculations. For comparison, additional simulations were performed as dynamic single and two-phase calculations. The steady state single phase calculations provided indications on preferred configurations for most above mentioned features. The results of the dynamic simulations supported the utilization of the computationally faster steady state model as a practical engineering tool. However, the two-phase model provides more truthful results especially with flows where a single phase does not determine the flow characteristics.

Value creation in project business relationships: Supplier and customer's perspectives

The purpose of this study is to analyze supplier’s value creation ability in project business in order to enhance customer’s business. In addition, the aim is to identify the role of business relationships in value creation and analyze the applicability of key account management in project business. The study considers value from the customer’s point of view. The concepts of value and value creation are widely discussed in marketing literature. Theory emphasizes the importance of value creation and business relationships in business markets. The empirical part of the study is conducted as a case study research. The empirical evidence is collected by interviewing one supplier organization and their three customer organizations. These companies operate in Finnish and global industrial markets. Data is collected through semi-structured interviews and analyzed by using qualitative content analysis. The study identifies several customer value drivers influencing on the value creation, which can be divided into product, service and relationship elements. One of the recognized value drivers is customer-supplier relationship. The findings show that a closer relationship enhances value creation possibilities and the key account management program allows effective managing of business relationships. As managerial implications, suppliers should seek to create continuous and conversational relationships with the key account customers.

Liiketoimintayksikön materiaalihallinnan nykytila ja sen tehostaminen materiaalien suoratoimituksilla

Tutkimuksen tarkoituksena on tutkia kansainvälisesti toimivan konserniyrityksen yhden liiketoimintayksikön materiaalinhallinnan ja siihen liittyvien toimintojen nykytilaa. Lisäksi tutkimuksessa selvitetään, miten materiaalinhallintaa varastoinnin osalta voidaan kehittää suoratoimitusmallin periaatetta hyödyntäen ja mitä säästöpotentiaaleja tämän kaltaiseen malliin liittyy kohdeorganisaation toimintaympäristö huomioiden. Tutkimuksen teoriaosion lähdeaineisto koostuu materiaalinhallinnan perusteosten lisäksi tieteellisistä artikkelijulkaisuista. Käytännönosuuden aineisto pohjautuu kohdeorganisaatiossa käytyihin keskusteluihin, tuotannonohjausjärjestelmästä saatuun tietoon ja omiin havaintoihin. Nykytilanteen analyysissä selvisi, että kohdeorganisaation varastointiin liittyy tehostamispotentiaalia erityisesti tila-, käsittely, ja työkustannusten osalta. Kohdeorganisaation varastoinnin tehostamista tutkittiin suoratoimitusmallin avulla. Suoratoimitusmallissa materiaalit eivät kierrä kohdeorganisaation pitämän välivaraston kautta, vaan ne toimitetaan toimittajan tiloista suoraan tuotannon välittömään tarpeeseen. Mallin avulla voidaan jakaa toimittajien kanssa sellaisia resursseja, joita molempien toiminta vaatii ja täten vapauttaa nykyistä varastointitilaa ja keventää sisäisen logistiikan kuormaa. Suoratoimitusmallin liittyvien hyötyjen kannalta on oleellista, että malliin valitaan sellaiset materiaalit, jotka sisältävät eniten potentiaalia niin säästö- kuin soveltuvuusnäkökulmasta. Valittujen kriteerien avulla kohdeorganisaation hankkimista materiaaleista löydettiin joukko materiaaleja, joiden avulla pystyttiin osoittamaan, että suoratoimitusmallin avulla on mahdollista saavuttaa kustannussäätöjä varastoinnin osalta.

Armourstone revetments : will standard design criteria prevent failure? /

Bank stabilization structures are used to prevent the loss of valuable land within the urban environment and the decision for the type of structure used depends on the properties of the stream. In the urban areas of Southern Ontario there is a preference for the use of armourstone blocks as bank stabilization. The armourstone revetment is a free standing stone structure with large blocks of stone layered vertically and offset from one another. During fieldwork at Forty Mile Creek in Grimsby, Ontario armourstone failure was identified by the removal of two stones within one column from the wall. Since the footer stones were still in place, toe scour was eliminated as a cause of failure. Through theoretical, field, and experimental work the process of suction has been identified as a mode of failure for the armourstone wall and the process of suction works similarly to quarrying large blocks of rock off bedrock streambeds. The theory of lateral suction has previously not been taken into consideration for the design of these walls. The physical and hydraulic evidence found in the field and studied during experimental work indicate that the armourstone wall is vulnerable to the process of suction. The forces exerted by the flow and the resistance of the block determine the stability of the armourstone block within the wall. The design of the armourstone wall, high surface velocities, and short pulses of faster flowing water within the profile could contribute to armourstone failure by providing the forces needed for suction to occur, therefore adjustments to the design of the wall should be made in order to limit the effect.

Elementary computer-mediated online distance education : identification of criteria for successful implementation and practice

This study had three purposes related to the effective implem,entation and practice of computer-mediated online distance education (C-MODE) at the elementary level: (a) To identify a preliminary framework of criteria 'or guidelines for effective implementation and practice, (b) to identify areas ofC-MODE for which criteria or guidelines of effectiveness have not yet been developed, and (c) to develop an implementation and practice criteria questionnaire based on a review of the distance education literature, and to use the questionnaire in an exploratory survey of elementary C-MODE practitioners. Using the survey instrument, the beliefs and attitudes of 16 elementary C'- MODE practitioners about what constitutes effective implementation and practice principles were investigated. Respondents, who included both administrators and instructors, provided information about themselves and the program in which they worked. They rated 101 individual criteria statenlents on a 5 point Likert scale with a \. point range that included the values: 1 (Strongly Disagree), 2 (Disagree), 3 (Neutral or Undecided), 4 (Agree), 5 (Strongly Agree). Respondents also provided qualitative data by commenting on the individual statements, or suggesting other statements they considered important. Eighty-two different statements or guidelines related to the successful implementation and practice of computer-mediated online education at the elementary level were endorsed. Response to a small number of statements differed significantly by gender and years of experience. A new area for investigation, namely, the role ofparents, which has received little attention in the online distance education literature, emerged from the findings. The study also identified a number of other areas within an elementary context where additional research is necessary. These included: (a) differences in the factors that determine learning in a distance education setting and traditional settings, (b) elementary students' ability to function in an online setting, (c) the role and workload of instructors, (d) the importance of effective, timely communication with students and parents, and (e) the use of a variety of media.

In danger of jammed minds: A deconstructive discourse analysis of the criteria for early onset schizophrenia and imagination in children's literature

The purpose of this research is to expose and complicate those discourses of childhood imagination as demonstrated in the diagnostic criteria for early onset schizophrenia by using an antipsychiatry perspective. This will be done by evaluating those discourses alongside those found in popular children’s literature, specifically, Harry Potter and The Philosopher’s Stone, Bridge to Terabithia, and A Wrinkle in Time. Once uncovered, the underlying power discourses were then exposed. This research will then employ a minor reading as provided by Deleuze and Guattari’s (1987) approach to minor literature to demonstrate the ways in which the child can subvert those dominant discourses. The potential of literature is evaluated for its ability to provide alternative modes of experience and lines of flight for the child subjected to the diagnostic criteria of schizophrenia.

Relative Egalitarianism and Related Criteria

We reconsider the problem of aggregating individual preference orderings into a single social ordering when alternatives are lotteries and individual preferences are of the von Neumann-Morgenstern type. Relative egalitarianism ranks alternatives by applying the leximin ordering to the distributions of (0-1) normalized utilities they generate. We propose an axiomatic characterization of this aggregation rule and discuss related criteria.
