An integrated vendor‐buyer inventory model with partial backordering
Authors: Moshrefi Fateh , Reza Akbari Jokar Mohammad 
Published: August 2012

PurposeThe purpose of this paper is to analyze the effects of supply chain coordination on inventory management while the retailer inventory cycle consists of a shortage period and the backorder rate linearly decreases as a function of shortage duration. It is intended to consider how on‐hand inventory and shortage durations are altered when the decisions are centralized.Design/methodology/approachMathematical modelling of inventory costs for the retailer and the vendor is used to formulate objective functions. The vendor sets his inventory period as an integer multiple (n) of the retailer inventory cycle in which the integer multiple is a decision variable. Solution spaces of models are analyzed to determine two other decision variables including, on‐hand inventory duration and shortage length.FindingsThe integrated model consists of a unique pseudo convex area when (n) is fixed and as a result, there is a unique minimum point. Based on numerical examples and sensitivity analysis, in most situations coordinated inventory management reduces total costs of the supply chain and cost reduction rate increase at larger production rates.Originality/valueThis paper is a combination between production‐inventory models in two‐stage supply chains and partial backordering, which has appeared in single inventory models. To the best of the authors' knowledge, no mathematical model has yet been proposed. Moreover, the benefits of synchronization are analyzed through numerical examples.

Authors: Chung Kim‐Choy , Holdsworth David K. 
Published: August 2012

PurposeThis study aims to investigate perceived risk and trustworthiness in relationship to the diffusion of innovation theory to understand the determinants of behavioural intent to adopt mobile commerce among the Y Generation. It also seeks to investigate the impact of culture on mobile commerce adoption.Design/methodology/approachFive hundred and thirty randomly distributed questionnaires in six tertiary education institutions in Kazakhstan, Morocco and Singapore were used. Multivariate analysis of variance was conducted using SPSS and structural equation modelling using AMOS 7.0 to test for construct validity and for hypothesis testing.FindingsPerceived risk, trustworthiness and Rogers' five perceived characteristics of innovation (namely, observability, trialability, compatibility, complexity, relative advantage) determined behavioural intent to adopt mobile commerce among the Y Generation. Culture had a moderating effect on these determinants in Kazakhstan and Morocco.Research limitations/implicationsThis study has not yet explored cost, goods offerings and payment systems that may influence users' intention to adopt mobile commerce. Differential experience of respondents with different mobile portals would have differential effect on the perceived ease of use of mobile commerce, affecting the result of this study.Practical implicationsThis study suggested that the Y Generation are concerned about privacy violation and risk associated with mobile commerce. Mobile service providers should consider trials and permission‐based mobile marketing to imbue trust in mobile commerce.Originality/valueThis study integrates trustworthiness and perceived risk with Rogers' DOI innovation characteristics, resulting in greater understanding of the behavioral intent to adopt mobile commerce among the Y Generation. Further, few studies delved into the comparative impact of culture on the behaviour intent to adopt mobile commerce among the Y Generation in Asian and African countries.
Investigating the effects of cosmeceutical product advertising in beauty‐care decision making
Authors: Meng Juan , Pan Po‐Lin 
Published: August 2012

PurposeIn response to the rapid growth of the cosmeceutical industry, this study aims to investigate young female consumers' confidence in cosmeceuticals and the perceived competency of cosmeceutical product advertising.Design/methodology/approachAn online survey of 224 young female participants was recruited from an online national young consumer panel from Zoomerang. This group of participants mirrored the characteristics of the largest segment in the cosmeceutical market in the USA.FindingsThe results suggest that the perceived information utility of cosmeceutical product advertising is the most significant factor in engaging young female consumers' interests and desire to try cosmeceuticals. Moreover, young female consumers' self‐evaluation on body esteem, their perceived effectiveness of product claims, their interests in reading such advertising, and their attitudes toward advertising jointly affect their likelihood to take cosmeceutical products. Not surprisingly, self‐evaluation on body esteem predicted a negative influence on product purchase intention. As their self‐evaluation on body esteem increases, the likelihood to purchase cosmeceuticals decreases.Originality/valueThe study adds insights on a fast‐growing, but understudied, product category, cosmeceutical products, to the research stream and expands the knowledge on the information utility of cosmeceutical product advertising on young female consumers.

Published: August 2012

PurposeA large number of East Asian economies have benefited from the diaspora employed in the large North American and European clusters. The diaspora acquired valuable skills, developed contacts and financial wealth. Much has been written about the professional and personal obstacles of brain circulation but scant work has been done to highlight the structural factors influencing brain circulation as well as diaspora strategies in the Malaysian context. This article aims to review the brain circulation theory and pertinent literature on Malaysian clusters and to highlight the structural factors inhibiting diaspora and flow of talent to Malaysia.Design/methodology/approachThis is a discussion paper on the issues surrounding diaspora strategies.FindingsOn the basis of the review of successful diaspora of China, India, Korea and Taiwan, cluster organizations should take independent initiatives to contact the diaspora networks abroad in order to leverage their skills, contacts and finances through alumni and virtual networks.Practical implicationSuccessful diaspora programs in China, Taiwan and India do not guarantee that imitation of those programs will result in success elsewhere.Originality/valueThe article reviews the pertinent literature and highlights the structural factors inhibiting diaspora and flow of talent to Malaysia.
The Muscles of the Infrapubic Abdominal Wall of a 6‐month‐old Crocodylus niloticus (Reptilia: Crocodylia)
Authors: Fechner R. , Schwarz‐Wings D. 
Published: August 2012

SummaryThe muscles of the infrapubic abdominal wall of crocodilians play an important role in their ventilatory mechanism. Yet the anatomy and homology of these muscles is poorly understood. To gain new insights into the anatomy of the crocodilian infrapubic abdominal wall, we dissected a specimen of Crocodylus niloticus. Origin and insertion of the muscles, as well as their arrangement relative to each other was examined in great detail. The findings were compared with those of other crocodilian taxa to detect potential variability of the muscles of interest. The homology of the muscles was studied by comparing the muscles of the crocodilian infrapubic abdominal wall with those of other diapsids. In Crocodylus niloticus, the infrapubic abdominal wall consists of four muscles: Musculus truncocaudalis, M. ischiotruncus, and Mm. rectus abdominis externus and internus. The arrangement of the muscles of the infrapubic abdominal wall of Crocodylus niloticus is consistent with that found in most other crocodilian taxa. In some crocodilian taxa, an additional muscle, M. ischiopubis, is found. In the remaining diapsids, only M. rectus abdominis is present. The crocodilian M. truncocaudalis, M. ischiotruncus and, if present, M. ischiopubis appear to be derivates of M. rectus abdominis; the development of those might be related to the evolution of the unique crocodilian ventilatory mechanism.

Published: August 2012

SummaryBackgroundVaptans may correct hyponatraemia and mobilise ascites through an increased excretion of water. The effect on clinical outcomes is debated.AimTo determine the effects of vaptans (tolvaptan, satavaptan and lixivaptan) on patients with cirrhosis and hyponatraemia or ascites.MethodsSystematic review of randomised controlled trials. The primary outcome measure was mortality. Electronic and manual searches were combined (April 2012). Data were extracted from published reports, online information from the Food and Drug Administration website or obtained through correspondence with authors and pharmaceutical companies. The primary meta‐analyses were performed using random effects models due to an expected clinical diversity.ResultsTwelve trials with a total of 2266 patients were included. Randomisation was adequate in all trials. Eight trials were double‐blind. Random effects meta‐analyses found no clear differences between vaptans and control groups regarding mortality (RR = 1.06, 95% CI = 0.90–1.26, I2 = 0%), variceal bleeding, hepatic encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome, or renal failure. Vaptans increased serum sodium levels (WMD = 1.8 mmol/L, 95% CI = 0.79–2.96) and lead to reductions in weight and the time to the first paracenthesis. Vaptans increased the risk of adverse events (RR = 3.97, 95% CI = 1.78–8.83), including an excessive urine volume (RR = 9.96, 95% CI = 1.38–71.68).ConclusionsVaptans have a small beneficial effect on hyponatraemia and ascites, but do not affect mortality, complications to cirrhosis or renal failure. The data do not support the routine use of vaptans in cirrhosis.

SummaryThirty myelofibrosis patients (21 males, nine females) with relapse (n = 27) or graft‐rejection (n = 3) after dose‐reduced allografting underwent a salvage strategy including donor lymphocyte infusions (DLIs) and/or second allogeneic haematopoietic stem cell transplantation (HSCT). Twenty‐six patients received a median number of three (range, 1–5) DLIs in a dose‐escalated mode starting with a median dose of 1·2 × 106 (range, 0·003–8 × 106) up to median dose of 40 × 106 T‐cells/kg (range, 10–130 × 106). 10/26 patients (39%) achieved complete response (CR) to DLIs. Acute (grade II‐IV) and chronic graft‐versus‐host (GvHD) disease occurred in 12% and 36% cases. Thirteen non‐responders to DLI and four patients who did not receive DLI due to graft‐rejection or acute transformation of the blast phase underwent a second allogeneic HSCT from alternative (n = 15) or the same (n = 2) donor. One patient (6%) experienced primary graft‐failure and died. Acute (II‐IV) and chronic GvHD were observed in 47% and 46% of patients. Overall responses after second HSCT were seen in 12/15 patients (80%: CR: n = 9, partial response: n = 3). The 1‐year cumulative incidence of non‐relapse mortality for recipients of a second allograft was 6%, and the cumulative incidence of relapse was 24%. After a median follow‐up of 27 months, the 2‐year overall survival and progression‐free survival for all 30 patients was 70% and 67%, respectively. In conclusion, our two‐step strategy, including DLI and second HSCT for non‐responding or ineligible patients, is an effective and well‐tolerated salvage approach for patients relapsing after reduced‐intensity allograft after myelofibrosis.
Input matching and patch use by native and invasive minnows
Authors: Wagner C. Michael , Grossman Gary D. 
Published: August 2012

AbstractWhen members of a population choose patches that maximise individual net energy gain without interference, they are input matching, a strategy derived from the ideal free distribution (IFD) that results in equal rewards across all patches. We investigated the input matching abilities of yellowfin shiner, a recent invader, and rosyside dace, a common native minnow, found inCoweetaCreek,NorthCarolina,USA. To test the species' relative input matching abilities, we varied food abundance within the range found in the natural habitat in a two‐patch laboratory stream to document the distribution of foragers when food densities differed in the ratio of 2:1. We then applied simpleIFDmodel predictions to determine whether the observed distribution of foragers was best described by (i) theIFD, (ii) differing competitive abilities or (iii) the ideal despotic distribution and/or other unequal competitor models, and to ascertain whether the invader demonstrated a superior ability to track resource distributions. Yellowfin shiner was more likely to move between patches, which resulted in increased ability to match the distribution of food when prey abundance increased. The distribution of rosyside dace between patches did not change in response to increased food abundance. Despite a considerable range of competitive abilities within intraspecific groups, the ‘equal competitors’IFDwas as good at predicting fish distributions as ‘unequal competitor’ models. The ability to track local resource availability in highly variable environments facilitates maximising energy intake and likely promoted the establishment of yellowfin shiner in a southern Appalachian stream.

Published: August 2012

SummaryThe effect of independent variables of microwave‐assisted extraction (MAE), extraction temperature (50–90 °C), microwave power (100–200 W), solvent concentration (methanol/water, 50–90%, v/v) and extraction time (1–27 min) on total phenolics and flavonoids contents as well as antioxidant activity of broccoli extracts was investigated. Response surface methodology was successfully applied for optimisation and the high correlation of the mathematical model indicated that a quadratic polynomial model could be used for optimisation of investigated responses. Considering the maximum amount of extracted total phenolics, total flavonoids and antioxidant activity expressed as ORAC value, the optimal conditions for all three investigated responses were obtained (temperature −71.11 °C; microwave power −167.03 W; solvent concentration −75.95%; and extraction time 16.34 min), which is in agreement with optimal conditions obtained for each investigated responses. The development of simultaneously MAE methods for total phenolics, total flavonoids and antioxidant activity of broccoli extracts might simplify assessment of broccoli as valuables source of antioxidants.

Published: August 2012

SummaryDrying kinetics of fresh daylily flower buds (Hemerocallis Citrine Baroni cv. Mengzihua) in a microwave oven at 60, 120, 180 and 240 W, respectively, were investigated. The results indicated that, drying rate increased at the initial time (a warm‐up period) and then decreased at the end time (a falling rate period) after reaching a plateau (a constant rate period). A third‐order polynomial model could well describe the relationships between effective diffusivity and moisture content, and the model's coefficients correlated linearly with microwave power level. A logistic model could well present the relationships between activation energy and moisture content. The curves of energy consumption vs. microwave power level indicated that in the initial phase of drying, the energy utilisation efficiency was almost the same at different microwave output power levels; however, at the end phase of drying, drying at lower microwave levels was worse in energy utilisation.
Optimising the ice cream formulation using basil seed gum (Ocimum basilicum L.) as a novel stabiliser to deliver improved processing quality
Authors: BahramParvar Maryam , Razavi Seyed M.A. , Mazaheri Tehrani Mostafa 
Published: August 2012

SummaryMixture design was used to determine the optimum ratio as well as concentration of basil seed gum (BSG), guar gum (GG) and carboxymethyl cellulose (CMC) in the formulation of ice cream stabilisers. Predicted equations and contour plots of physicochemical responses were also generated. Generally, increasing the ratio of BSG in gums mixture increased the apparent viscosity of ice cream mixes and decreased the melting rate. Increasing the proportion of GG at concentration of 0.35% enhanced overrun of samples. High ratios of BSG at concentration of 0.35% and CMC at concentration of 0.15% increased the fat destabilisation in ice creams. Combination of 84.31% BSG and 15.69% CMC at concentration of 0.35% proposed as optimum formulation which verified in practice. Introducing BSG as a novel source of stabiliser could be promising as alternative and improve the quality and diversity of ice cream and related products.

SummaryResponse surface methodology (RSM) ofBox–Behnken design with 27 experimental runs and the desirability function method were used in the osmotic dehydration process ofChinese ginger (ZingiberofficinaleRoscoe) slices in ternary solution of water, sucrose and sodium chloride for maximising water loss (WL), rehydration ratio (RR) and total phenolic content (TPC) and minimising solute gain (SG) and hunter colour change (HCC) of dehydrated product. The results indicated that the optimum operating conditions were found to be process duration of 102 min, solution temperature of 30 °C, solution concentration of 50Brix sucrose + 7.31% sodium chloride and solution to food ratio of 8:1 (w/w). Under this condition, theWL,SGandTPCwere 58.8% (wb), 12.56% (wb) and 1.46% (db), while itsRRandHCCwere 1.59 and 6.55, respectively. The immersion time was the most significant variable forWL,HCC,SGandRR, and forTPCit was temperature (P < 0.05).

Published: August 2012

SummaryPeanut meal, the primary by‐product of commercial oil crushing operations, is an excellent source of protein although aflatoxin contamination often limits applications for this material. Naturally aflatoxin‐contaminated (59 ppb) peanut meal dispersions were adjusted to pH 2.1 or pH 9.1, with or without additional protease and/or a clay absorbent, and the resulting soluble extracts derived from these dispersions were spray dried. Clay addition during processing minimally affected spray‐drying yields, protein powder solubility or antioxidant capacities, whereas these properties were significantly altered by pH and protease treatments. Spray‐dried hydrolysates produced from peanut meal treated with clay contained significantly less aflatoxin than hydrolysates produced without clay; the effects of pH or enzyme on aflatoxin content were minimal. Peanut meal treated with Alcalase, and clay yielded spray‐dried hydrolysates with enhanced antioxidant capacity and increased solubility compared to unhydrolysed controls and had aflatoxin levels below 1 ppb.

Authors: Tananuwong Kanitha , Tangsrianugul Nuttinee 
Published: August 2012

SummaryInfluences of the conditions of raw rice storage and cooking on parameters related to colour and antioxidant activities of organic hulled red fragrant rice were investigated. Raw rice samples were vacuum‐packed in oriented polypropylene/aluminium/linear low‐density polyethylene or nylon/linear low‐density polyethylene pouches and stored at ambient temperature or 15 °C up to 12 months. Cooked samples were prepared from aged raw samples. Kernel colour, total anthocyanin content (TAC) of acidic methanolic extracts as well as total phenolic content (TPC), reducing power (RP) and radical scavenging activity (RSA) of methanolic extracts and enzymatically digested samples were maintained during 12‐month storage, regardless of packaging materials and storage temperatures. Cooked kernels had larger L value, lower a and b values, and greater TAC (dry basis), comparing with the raw rice. Cooking caused drastic decrease in TPC, RP and RSA of methanolic extracts. Nevertheless, less negative impacts of cooking were found for enzymatically digested samples.
