Identifying attendance motives for an international league fixture
Authors: Reimers Vaughan , Chao Chih-Wei (Fred) , Speechley Kim 
Published: November 2017

PurposeWhilst the impact of motives on sports attendance has received due scholarly attention, one context that appears to have been overlooked is the growing trend towards playing domestic league fixtures in an international setting. The purpose of this paper is to address this oversight by exploring how four different categories of motives distinguished attendees from non-attendees for an Australian Rules football game played in New Zealand.Design/methodology/approachA stadium-intercept method at a St Kilda home game was used for the purposes of data collection. In total, 2,000 survey invitations had been distributed. Of these, 381 usable online surveys were received. The resulting data were analysed using structural equation modelling.FindingsThis study found that the lower fans’ expectations of their team winning, the less likely they were to travel internationally to watch their team play. Furthermore, it also support that sport tourism is influenced not only by the event itself but also non-event attractions offered by the host destination image.Research limitations/implicationsThe limitation applies to the research context in which the respondents were selected from one of the two competing teams.Practical implicationsThis study confirms the importance of “special occasion” and highlights that an Australian Football League game played in New Zealand on ANZAC Day should continue to serve as a special occasion due to the historical significance of that day.Originality/valueThe results from this study confirm the importance of adding a fourth category of motives – contextual factors – to the existing list of push, pull and sports motives. The findings also support the obvious distinction between attending a domestic event vs attending an international one.

Authors: Ramadani Veland , Zendeli Donika , Gerguri-Rashiti Shqipe , Dana Leo-Paul 
Published: November 2017

Purpose
This paper aims to study and compare variables such as location, industry, socio-demographics and business factors of several companies located in Western Macedonia.

Design/methodology/approach
Research method is based on primary data the authors collected through questionnaires and secondary data obtained from State Statistical Office. Besides, the research sums up data classification of companies in the aspect of geomarketing and how location determinants and geo-information of certain cities can influence their business development and decision-making. Lastly, the results of data and Structural Equation Modeling integration are presented.

Findings
Since Republic of Macedonia is more than 25 years in transition, experts have often foreseen that companies in their country most of the time make intuitive decisions and do not take into account many elements during decision-making process in the business aspect. But on the other hand, results reveal interesting facts about companies involved in their research. For a majority of companies, the influence of geomarketing on business development is positive as long as during decision-making process its determinants have been taken into consideration and reviewed.

Practical implications
The paper helps the entrepreneurs to develop their businesses and decision-making process based on geomarketing determinants.

Originality/value
This is the first paper that investigates and compares variables such as location, industry, socio-demographics and business factors of companies located in Macedonia.
Effect of population density and network availability on deployment of broadband PPDR mobile network service
Authors: Peltola Matti , Hämmäinen Heikki 
Published: November 2017

Purpose
The purpose of the paper is to define the best deployment alternatives for a public protection and disaster relief (PPDR) mobile network service – the implementation alternatives being either a dedicated network, a commercial network or a hybrid of the two network types. The selection criteria are based on the social benefits that the PPDR mobile service is expected to bring to society. The critical parameters are population density and service availability, which both directly relate to the socioeconomic benefits achieved by providing broadband (BB) mobile services in various demographic areas.

Design/methodology/approach
A causal loop model has been developed to define the socioeconomic benefits of the PPDR network, the parameters being population density, service availability, socioeconomic value of the service and the costs of the network. The network solution alternatives are studied using the Finnish PPDR network as a reference – analysing various areas of the country with differing population densities from remote, rural and more densely populated suburban and urban areas.

Findings
Socioeconomic value is a common measure for assessing the value of governmental investments; population density has a strong impact on the optimum deployment alternatives as the socioeconomic value is directly proportional to this variable. The flat nationwide fee of the mobile users means that the users are subsidised in sparsely populated areas – and overcharged in densely populated areas. This is the main reason why the commercial network seems to be most feasible in rural areas, whereas the dedicated network works best in urban areas. Based on the case study, the commercial network is most preferable up to the point when the population density reaches 50-125 persons/km2. After that point, the dedicated network becomes more appropriate. Proposals are being made to improve the availability of the commercial networks enabling them to serve as a PPDR network: ensuring priority functionality and a protected power supply; allowing PPDR subscribers the exclusive use of one of the 700 MHz spectrum bands in restricted, critical areas; and extending use of the existing narrowband PPDR network in areas where communication availability is crucial.

Originality/value
On the one hand, the financing of BB PPDR mobile networks is an unresolved issue in many countries. On the other hand, the ability of commercial BB networks to provide better quality of service is improving, making viable the alternative to subscribe for radio service from a commercial operator. Therefore, the feasibility study on how to provide an optimum mobile BB service for PPDR organisations is of real value at this time.
Dynamics analysis of a production-inventory control system with two pipelines feedback
Authors: AL-Khazraji Huthaifa , Cole Colin , Guo William 
Published: November 2017

Purpose
The purpose of this study is to propose a new dynamic model of a production-inventory control system. The objective of the new model is to maximise the flexibility of the system so that it can be used by decision makers to design inventory systems that adopt various strategies that provide a balance between reducing the bullwhip effect and improving the responsiveness of inventory performance.

Design/methodology/approach
The proposed production-inventory control system is modelled and analysed via control theory and simulations. The production-inventory feedback control system is modelled through continuous time differential equations. The simulation experiments design is conducted by using the state-space model of the system. The Automatic Pipeline Inventory and Order-Based Production Control System (APIOBPCS) model is used as a benchmark production-inventory control system.

Findings
The results showed that the Two Automatic Pipelines, Inventory and Order-Based Production Control System (2APIOBPCS) model outperforms APIOBPCS in terms of reducing the bullwhip effect. However, the 2APIOBPCS model has a negative impact on Customer Service Level. Therefore, with careful parameter setting, it is possible to design control decisions to be suitably responsive while generating smooth order patterns and obtain the best trade-off of the two objectives.

Research limitations/implications
This research is limited to the dynamics of single-echelon production-inventory control systems with zero desired inventory level.

Originality/value
This present model is an extension and improvement to Towill’s (1982) and John et al.’s (1994) work, since it presents a new dynamic model of a production-inventory control system which utilises an additional flow of information to improve the efficiency of order rate decisions.

Carbon and Nitrogen Stable Isotope Analyses of Ephedra Plant and Ephedrine Samples and Their Application For Methamphetamine Profiling
Authors: Liu Cuimei , Liu Peipei , Jia Wei , Fan Yingfeng 
Published: November 2017

AbstractIn this study, stable isotope ratio analysis was used to track the precursor information of methamphetamine. The δ13C and δ15N values of 30 nature ephedra plants, 12 synthetic ephedrine/pseudoephedrine (ephedrine), 14 natural ephedrine, and 987 seized methamphetamine samples were measured and compared. Due to different weather and earth conditions, the δ13C and δ15N values of ephedra plants grown in the east and the west of Inner Mongolia showed great difference. The δ15N values of ephedra plants were consistent with related ephedrine extracted from them. Moreover, the criteria to infer the synthetic origin of ephedrine were set up after the analysis of natural and synthetic ephedrine samples. Finally, the precursor origins of 949 seized methamphetamine samples synthesized by Emde and Nagai method were tentatively inferred. Influenced by different preprecursors, the δ13C values of seized methamphetamine samples that synthesized from P2P also showed great difference, and this result is consistent with the reported data.
Density‐independent reproductive success of the hemiparasitic plant Striga hermonthica, despite positive and negative density‐dependent phases

Published: November 2017

AbstractThe hemiparasite Striga hermonthica is a major constraint to smallholder farmer livelihoods and food security in sub‐Saharan Africa. A better understanding of its life‐cycle can help developing more effective management strategies. Here, we studied density dependence in S. hermonthica on Sorghum bicolor. We exposed two genotypes of S. bicolor that differed in the level of tolerance and resistance to S. hermonthica to a range of seed densities of the parasite. We evaluated multiple host and parasite performance parameters through periodic, destructive harvests and related these to the initial seed density using model selection. Initially, the probability for attachment was positively density‐dependent, suggesting facilitation of new infections. However, at host maturity, S. hermonthica infection probability showed strong negative density dependence, indicating severe competition, in particular in the early developmental stages. Although parasite shoot dry weight showed a strong negative density dependence at host maturity, flower production per parasite exhibited positive density dependence again, suggesting compensation. The two host genotypes had similar responses to increased parasite densities, indicating differences between the genotypes in tolerance but not resistance. Consequently, despite density dependence in life‐cycle components, the per capita reproductive output of S. hermonthica, R0 (flowers seed−1) was density‐independent. Apparently, management of the hemiparasite can neither benefit from a negatively density‐dependent bottleneck, nor from a positively density‐dependent Allee effect. The most promising suggestion to obtain S. hermonthica population decline (R0 < 1) and long‐term control is to increase host shading by growing a vigorous, competitive crop.
Predators and competitors of the mountain pine beetleDendroctonus ponderosae(Coleoptera: Curculionidae) in stands of changing forest composition associated with elevation

Published: November 2017

AbstractThe mountain pine beetleDendroctonus ponderosae(Coleoptera: Curculionidae) is an irruptive tree‐killing bark beetle native to pine stands in western North America. The primary hosts are lodgepole and ponderosa pines. Recent rising temperatures, however, have allowed these beetles to survive at higher elevations more commonly than in the past, thus threatening whitebark pine, a keystone species of high elevation ecosystems and a highly susceptible host.The extent to which risk in whitebark pine stands may be mitigated by predators or competitors is unknown. We compared the communities of coleopteran predators and competitors ofD. ponderosaein sites of varying elevation and species composition in Montana and Wyoming, U.S.A. Sites were selected for low to moderate levels of tree mortality, where the potential of natural enemies to preventD. ponderosaefrom transitioning into outbreaks would be most relevant. Insect populations were evaluated using unbaited flight‐intercept panel traps and pheromone‐baited multiple funnel traps.Only the predatory beetle speciesThanasimus undatulus(Coleoptera: Cleridae) was captured in these non‐outbreak stands. Based on the pheromone‐baited traps, predator load was higher at low‐elevation stands dominated by lodgepole pine than high‐elevation stands dominated by whitebark pine.Phloeophagous insects were more prevalent in the mid‐ and higher‐elevation sites, although most of the species captured would not likely compete substantially for resources withD. ponderosae. We also observed differences in species assemblages between the Montana and Wyoming sites, as well as differing utilities of baited and unbaited traps at low versus moderate tree mortality levels.

Published: November 2017

AbstractBackgroundEarly‐life sensitization to indoor allergens predicts asthma development. The aim of this study was to compare allergen concentrations in day‐care centers (DCC) with those in private homes.MethodsSettled airborne dust was collected 4 times a year from 20 German DCC (620 samples) and from the homes of children and day‐care workers (602 samples) using electrostatic dust collectors (EDC). The samples were analyzed with fluorescence enzyme immunoassays recognizing domestic mite allergens (DM), Fel d 1, Can f 1, and Mus m 1. Pet allergen thresholds that discriminate samples from homes with cats or dogs from those without were calculated using receiver‐operating characteristics. Influences on allergen levels were analyzed using multilevel models.ResultsAllergen loads were on average higher in DCC than in homes. In DCC, 96% of the samples were positive for DM, 95% for Can f 1, 90% for Fel d 1, and 83% for Mus m 1. In homes, 84% contained DM, 48.5% Can f 1, 33% Fel d 1, and 43% Mus m 1. The threshold level for homes with dogs was 75 ng/m² Can f 1 (96.8% sensitivity, 96% specificity), and the threshold level for homes with cats was 46 ng/m² Fel d 1 (92% sensitivity, 94.9% specificity). In DCC, Can f 1 and Fel d 1 loads were higher than these thresholds in 37% and 54% of the samples, respectively. Allergen levels were significantly influenced by the season and room type; however, carpets on floors had no influence.ConclusionsMite, mouse, cat, and dog allergens were mostly higher in DCC than in homes. Exposure to dog and cat allergens in DCC often reached levels of households with pets.

AbstractBackgroundPrevious studies showed controversial results for the influence of pregnancy‐related and perinatal factors on subsequent respiratory and atopic diseases in children. The aim of this study was to assess the association between perinatal variables and the prevalence of asthma, bronchial hyperreactivity (BHR), flexural eczema (FE), allergic rhinitis, and sensitization in childhood and early adulthood.MethodsThe studied population was first examined in Munich and Dresden in 1995/1996 at age 9‐11 years. Participants were followed until age 19‐24 years using questionnaires and clinical examinations. Associations between perinatal data and subsequent atopic diseases were examined using logistic regression analyses adjusting for potential confounders.ResultsCesarean section was statistically significantly associated with BHR in early adulthood (odds ratio 4.8 [95% confidence interval 1.5‐15.2]), while assisted birth was associated with presence of asthma symptoms in childhood (2.2 [1.2‐3.9]), FE symptoms (2.2 [1.2‐4.3]) and doctor's diagnosis of atopic dermatitis (1.9 [1.0‐3.4]) in childhood, and sensitization in early adulthood (2.2 [1.1‐4.3]). Lower birth length (1.9 [1.1‐3.2]), lower birthweight (0.5 [0.3‐0.9]), and higher birthweight (0.6 [0.4‐1.0]) were predictive of sensitization in early adulthood compared to average birth length and birthweight, respectively. None of the other perinatal factors showed statistically significant associations with the outcomes.ConclusionsOur results indicate that children who are born by cesarean section and especially by assisted birth, might be at greater risk for developing asthma, FE, and sensitization and should hence be monitored. Prenatal maternal stress might partly explain these associations, which should be further investigated.

Published: November 2017

SummaryIn the mantle cell lymphoma (MCL)‐002 study, lenalidomide demonstrated significantly improved median progression‐free survival (PFS) compared with investigator's choice (IC) in patients with relapsed/refractory MCL. Here we present the long‐term follow‐up data and results of preplanned subgroup exploratory analyses from MCL‐002 to evaluate the potential impact of demographic factors, baseline clinical characteristics and prior therapies on PFS. In MCL‐002, patients with relapsed/refractory MCL were randomized 2:1 to receive lenalidomide (25 mg/day orally on days 1–21; 28‐day cycles) or single‐agent IC therapy (rituximab, gemcitabine, fludarabine, chlorambucil or cytarabine). The intent‐to‐treat population comprised 254 patients (lenalidomide, n = 170; IC, n = 84). Subgroup analyses of PFS favoured lenalidomide over IC across most characteristics, including risk factors, such as high MCL International Prognostic Index score, age ≥65 years, high lactate dehydrogenase (LDH), stage III/IV disease, high tumour burden, and refractoriness to last prior therapy. By multivariate Cox regression analysis, factors associated with significantly longer PFS (other than lenalidomide treatment) included normal LDH levels (P < 0·001), nonbulky disease (P = 0·045), <3 prior antilymphoma treatments (P = 0·005), and ≥6 months since last prior treatment (P = 0·032). Overall, lenalidomide improved PFS versus single‐agent IC therapy in patients with relapsed/refractory MCL, irrespective of many demographic factors, disease characteristics and prior treatment history.
