Applying Trained Skills on the Job: The Importance of the Work Environment

The influence of the work environment on the transfer of newly trained supervisory skills was examined. Participants were 505 supermarket managers from 52 stores. The work environment was operationalized in terms of transfer of training climate and continuous-learning culture. Climate and culture were hypothesized to have both direct and moderating effects on posttraining behaviors. Accounting for pretraining behaviors and knowledge gained in training, the results from a series of LISREL analyses showed that both climate and culture were directly related to posttraining behaviors. In particular, the social support system appeared to play a central role in the transfer of training. Moderating effects were not found. Implications for enhancing the transfer of training are discussed.

Analisi e ottimizzazione del flusso di approvvigionamento in una produzione su commessa: il caso CT Pack S.r.l.

La tesi ha l'obiettivo di analizzare e ottimizzare i flussi di approvvigionamento in un'azienda che produce su commessa: CT Pack S.r.L, specializzata nella realizzazione di macchine automatiche per il packaging di biscotti, gelato e cioccolato. Per raggiungere l'obiettivo si è preso come riferimento il modello proposto dal BPR (Business Process Reengineering): sono stati analizzati i principali attori coinvolti, in particolare fornitori e magazzino, mediante l'uso di KPI definiti ad hoc. Sulla base di questi sono stati individuati due processi critici: il primo riguarda la gestione del magazzino, che presenta un'elevata quantità di codici non movimentati anche a causa del processo di gestione del materiale avanzato al termine di ciascuna commessa; il secondo riguarda il materiale a consumo, che impiega i magazzinieri per un tempo eccessivo, è caratterizzato da giacenze per il 30% non movimentate e da supermarket collocati in officina ridondanti e caratterizzati da bassi tassi di utilizzo (anche sotto il 50%). Per risolvere questi problemi ed effettuare una riprogettazione si fa affidamento agli strumenti proposti dal project management: si imposta quindi un progetto che ha l'obiettivo di ridurre nel breve periodo il valore di magazzino mediante lo smaltimento attraverso diverse vie di codici non utilizzati e agisce nel lungo periodo per evitare che le criticità si ripropongano. Mediante la riprogettazione della gestione dei resi di produzione si prevede un maggior controllo, grazie al lavoro congiunto di ufficio tecnico e ufficio acquisti. La nuova gestione del materiale a consumo ha in se alcune delle tecniche proposte dalla lean production (il kanban, per esempio) e integra il fornitore nella catena di approvvigionamento, garantendo un maggior controllo sulle quantità, un risparmio di circa 7 h/mese di lavoro per i magazzinieri e una riduzione delle giacenze del 46%.

Razionalizzazione di un magazzino componentistica per linee di assemblaggio di segnali aeroportuali: il caso Ocem Airfield Technology

Questa tesi si propone di illustrare il lavoro da me svolto presso l’azienda Ocem Airfield Technology all’interno del magazzino componentistica mirato alla riorganizzazione del supermarket delle linee di assemblaggio nell’ottica della minimizzazione dei tempi di prelievo. La continua ricerca di flessibilità sulla base delle esigenza della clientela ha un drastico effetto sul magazzino e sulla sua gestione. Il magazzino rappresenta un elemento estremamente oneroso nel bilancio aziendale e contribuisce per il 20% ai costi interni dell’impresa. Hanno un ruolo cruciale nel funzionamento aziendale: i magazzini sono il luogo di attesa per i prodotti dal punto di origine a quello di consumo, garantiscono l’immagazzinamento e lo stoccaggio della merce ed infine sono un driver fondamentale per ridurre l’incertezza. Tra le attività più costose si colloca il prelievo frazionato della merce o order picking, responsabile del 55% dei costi operativi logistici. Nell'ambito Ocem è stato implementato un progetto per la riduzione dei tempi di prelievo ispirandosi a modelli nati in letteratura. Il progetto inizialmente è stato testato su una linea pilota a bassi volumi per monitorare i possibili vantaggi. Una volta confermata la riduzione effettiva dei tempi di prelievo, il progetto è stato replicato con le opportune modifiche sulle restanti linee di assemblaggio raggiungendo incrementi di efficienza significativi. Il parametro adottato come performance index è stata la riduzione percentuale del tempo di prelievo dall’as-is al to-be.

Análise da gestão da cadeia de suprimentos de um supermercado varejista através da utilização do modelo SCOR

In the last decade the complexity of the environment in which organizations are embedded increased dramatically, having on one side the increasingly demanding consumers in regard to the quality and value of the product and the other companies with the need to reduce operating costs in order to achieve greater profitability, without this there is a downturn in growth or market share powers. In this context the necessity of effectively structuring actions relating to the line with the operational work processes so that business objectives are achieved organizational strategic planning, ensuring the competitiveness of the organization. This study aims to analyze how you have made the management of the supply chain in a grocery retailer in the light of guidelines of Supply Chain Management by using the SCOR model. For realization of this study a survey was needed, classified according to their goals, exploratory and descriptive as to its procedure, document, field and case study. Thus, the processing of data will be qualitative merit, using the thematic categorical analysis of Bardin (1977). Thus, to obtain data interviews together the operational and strategic management of a company that was named Supermarket Omega were performed. After analyzing the information obtained is perceived that there is an effort of the organization enhance its management of the supply chain. However, there is a lack of alignment between the various areas that compose it. About their work processes, we stress that the focus of the company is still very directed on sailing than profitability, although it is undergoing a transformation in its organizational culture However, records the existence of many improvement projects in developing. Thus, it can be noticed that there is some consistency between the assumptions of the SCOR model and applied within the supply chain Omega Supermarket, although a greater effort to better align with the model still needs to be studied

The impact of cooking methods on the nutritional quality and safety of chicken breaded nuggets

The impact of cooking methods (industrial pre-frying, deep-fat frying and baking) on the nutritional quality and safety of chicken breaded nugget samples from supermarket and commercial brands was evaluated. The changes in the quality characteristics (nutritional composition, fatty acids profile, cholesterol and salt) of the fried food and frying oil, after ten consecutive frying operations, were evaluated. The total fat content of nuggets varied between 10.9 and 22.7 g per 100 g of edible portion and the salt content ranged from 0.873 to 1.63 g per 100 g. Taking into account one portion of nuggets, the daily intake of salt can reach 49%, which can have a significant impact on the health of those who regularly consume this type of food, especially considering the prevalence of hypertension around the world. The analysed chicken breaded nuggets are rich in unsaturated fatty acids, which have been related with potential health benefits, namely regarding cardiovascular diseases. The cholesterol content of baked samples was two times higher when compared with the fried ones. The trans fatty acids and polar compounds contents of the frying oil used for frying significantly increased, but the values were still away from the maximum recommended by legal entities for its rejection. From a nutritional point of view, it is possible to conclude that the applied cooking methods can significantly influence the nutritional quality and safety of the analysed chicken breaded nuggets. This study will contribute to important knowledge on how the applied cooking methods can change the nutritional quality and safety of foods, namely of chicken nuggets, and can be very useful for dietary recommendations and nutritional assessment.

Ethanolic extracts from three commercial edibe mushrooms: determination of ergosterol contente and evaluation of bioactives properties

Mushrooms are rich in several bioactive metabolites among them are phenolic compounds, terpenoids, polysaccharides, lectins, and steroids including mycosterols, namely ergosterol [1]. Ethanolic extracts prepared by maceration of several mushroom species have been recently described as having antiinflammatory properties [2]. In the present work, ethanolic extracts of Agaricus bisporus L., Lentinus edodes (Berk.) Pegler and Pleurotus ostreatus (Jacq. ex Fr.) P.Kumm., purchased from a local supermarket in the Northeast of Portugal, were obtained by Soxhlet and chemically characterized in terms of ergosterol content by HPLC-UV. The antioxidant properties of these extracts were evaluated through DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity (RSA), reducing power (RP), p. carotene bleaching inhibition (CBI) and lipid peroxidation inhibition in TBARS (thiobarbituric acid reactive substances) assay (LPI); the antioxidant activity of ergosterol was also evaluated by the DPPH assay. The anti-inflammatory activity of the same extracts and ergosterol was evaluated in LPS (lipopolysaccharide) stimulated RAW 264.7 macrophages, through the inhibition of NO production. A. bisporus revealed the highest content in ergosterol (44.8 ± 0.4 mg/ g extract) followed by P. ostreatus (34 ± 3 mg/ g extract) and finally L. edodes (8.9 ± 0.1 mg/ g extract). A. bisporus showed the highest RSA, RP and CBI (EC50 values= 7.0 ± 0.8, 2.3 ± 0.1 and 1.4 ± 0.1 mg/mL, respectively), while L. edodes presented the highest LPI (2.5 ± 0.1 mg/mL ); ergosterol revealed higher RSA (0.46±0. 0 I mg/mL) than the extracts. Concerning the anti-inflammatory potential, the most efficient species was L. edodes (lC50 value = 164 ± 16 J.lg/mL), followed by A. bisporus (185 ± 16 J.lg/mL) and finally P. ostreatus (290 ± 10 J.lg/mL). However, ergosterol presented lower activity (338 ± 23 J.lg/mL) due to its low solubility in the culture medium. The higher antioxidant properties displayed by A. bisporus can be related with its higher ergosterol content, while in the anti-inflammatory activity this relation cannot be established also due to the low solubility of ergosterol in the cells culture medium, decreasing the ergosterol availability. More studies are being conducted regarding the ergosterol solubility. Several compounds have been implicated in the bioactivity of mushrooms and in this study we have found that ergosterol can give an important contribution.

Economic evaluation of price discounts and skill-building strategies on purchase and consumption of healthy food and beverages: The SHELf randomized controlled trial

OBJECTIVE: Pricing strategies are a promising approach for promoting healthier dietary choices. However, robust evidence of the cost-effectiveness of pricing manipulations on dietary behaviour is limited. We aimed to assess the cost-effectiveness of a 20% price reduction on fruits and vegetables and a combined skills-based behaviour change and price reduction intervention. DESIGN AND METHODS: Cost-effectiveness analysis from a societal perspective was undertaken for the randomized controlled trial Supermarket Healthy Eating for Life (SHELf). Female shoppers in Melbourne, Australia were randomized to: (1) skill-building (n = 160); (2) price reductions (n = 161); (3) combined skill-building and price reduction (n = 161); or (4) control group (n = 161). The intervention was implemented for three months followed by a six month follow-up. Costs were measured in 2012 Australian dollars. Fruit and vegetable purchasing and consumption were measured in grams/week. RESULTS: At three months, compared to control participants, price reduction participants increased vegetable purchases by 233 g/week (95% CI 4 to 462, p = 0.046) and fruit purchases by 364 g/week (95% CI 95 to 633, p = 0.008). Participants in the combined group purchased 280 g/week more fruits (95% CI 27 to 533, p = 0.03) than participants in the control group. Increases were not maintained six-month post intervention. No effect was noticed in the skill-building group. Compared to the control group, the price reduction intervention cost an additional A$2.3 per increased serving of vegetables purchased per week or an additional A$3 per increased serving of fruit purchased per week. The combined intervention cost an additional A$12 per increased serving of fruit purchased per week compared to the control group. CONCLUSIONS: A 20% discount on fruits and vegetables was effective in promoting overall fruit and vegetable purchases during the period the discount was active and may be cost-effective. The price discount program gave better value for money than the combined price reduction and skill-building intervention. The SHELf trial is registered with Current Controlled Trials Registration ISRCTN39432901.

The comparative cost of food and beverages at remote Indigenous communities, Northern Territory, Australia

OBJECTIVE: To determine the average price difference between foods and beverages in remote Indigenous community stores and capital city supermarkets and explore differences across products.

METHODS: A cross-sectional survey compared prices derived from point-of-sale data in 20 remote Northern Territory stores with supermarkets in capital cities of the Northern Territory and South Australia for groceries commonly purchased in remote stores. Average price differences for products, supply categories and food groups were examined.

RESULTS: The 443 products examined represented 63% of food and beverage expenditure in remote stores. Remote products were, on average, 60% and 68% more expensive than advertised prices for Darwin and Adelaide supermarkets, respectively. The average price difference for fresh products was half that of packaged groceries for Darwin supermarkets and more than 50% for food groups that contributed most to purchasing.

CONCLUSIONS: Strategies employed by manufacturers and supermarkets, such as promotional pricing, and supermarkets' generic products lead to lower prices. These opportunities are not equally available to remote customers and are a major driver of price disparity.

IMPLICATIONS: Food affordability for already disadvantaged residents of remote communities could be improved by policies targeted at manufacturers, wholesalers and/or major supermarket chains.

Shopsmart 4 health: results of a randomized controlled trial of a behavioral intervention promoting fruit and vegetable consumption among socioeconomically disadvantaged women

BACKGROUND: Behavioral interventions show potential for promoting increased fruit and vegetable consumption in the general population. However, little is known about their effectiveness or cost-effectiveness among socioeconomically disadvantaged groups, who are less likely to consume adequate fruit and vegetables. OBJECTIVE: This study investigated the effects and costs of a behavior change intervention for increasing fruit and vegetable purchasing and consumption among socioeconomically disadvantaged women. DESIGN: ShopSmart 4 Health was a randomized controlled trial involving a 3-mo retrospective baseline data collection phase [time (T) 0], a 6-mo intervention (T1-T2), and a 6-mo no-intervention follow-up (T3). Socioeconomically disadvantaged women who were primary household shoppers in Melbourne, Australia, were randomly assigned to either a behavior change intervention arm (n = 124) or a control arm (n = 124). Supermarket transaction (sales) data and surveys measured the main outcomes: fruit and vegetable purchases and self-reported fruit and vegetable consumption. RESULTS: An analysis of supermarket transaction data showed no significant intervention effects on vegetable or fruit purchasing at T2 or T3. Participants in the behavior change intervention arm reported consumption of significantly more vegetables during the intervention (T2) than did controls, with smaller intervention effects sustained at 6 mo postintervention (T3). Relative to controls, vegetable consumption increased by ∼0.5 serving · participant(-1) · d(-1) from baseline to T2 and remained 0.28 servings/d higher than baseline at T3 among those who received the intervention. There was no intervention effect on reported fruit consumption. The behavior change intervention cost A$3.10 (in Australian dollars) · increased serving of vegetables(-1) · d(-1)CONCLUSIONS: This behavioral intervention increased vegetable consumption among socioeconomically disadvantaged women. However, the lack of observed effects on fruit consumption and on both fruit and vegetable purchasing at intervention stores suggests that further investigation of effective nutrition promotion approaches for this key target group is required. The ShopSmart 4 Health trial was registered at www.isrctn.com as ISRCTN48771770.

ArmA methyltransferase in a monophasic Salmonella enterica isolate from food

The 16S rRNA methyltransferase ArmA is a worldwide emerging determinant that confers high-level resistance to most clinically relevant aminoglycosides. We report here the identification and characterization of a multidrug-resistant Salmonella enterica subspecies I.4,12:i:- isolate recovered from chicken meat sampled in a supermarket on February 2009 in La Reunion, a French island in the Indian Ocean. Susceptibility testing showed an unusually high-level resistance to gentamicin, as well as to ampicillin, expanded-spectrum cephalosporins and amoxicillin-clavulanate. Molecular analysis of the 16S rRNA methyltransferases revealed presence of the armA gene, together with bla(TEM-1), bla(CMY-2), and bla(CTX-M-3). All of these genes could be transferred en bloc through conjugation into Escherichia coli at a frequency of 10(-5) CFU/donor. Replicon typing and S1 pulsed-field gel electrophoresis revealed that the armA gene was borne on an ~150-kb broad-host-range IncP plasmid, pB1010. To elucidate how armA had integrated in pB1010, a PCR mapping strategy was developed for Tn1548, the genetic platform for armA. The gene was embedded in a Tn1548-like structure, albeit with a deletion of the macrolide resistance genes, and an IS26 was inserted within the mel gene. To our knowledge, this is the first report of ArmA methyltransferase in food, showing a novel route of transmission for this resistance determinant. Further surveillance in food-borne bacteria will be crucial to determine the role of food in the spread of 16S rRNA methyltransferase genes worldwide.
