Cyclist head and facial injury risk in relation to helmet fit: a case-control study
Authors: Romanow NR , Hagel BE , Williamson J , Rowe BH
Published: October 2020

Introduction

We examined the effect of bicycle helmet fit and position on head and facial injuries.

Methods

Cases were helmeted cyclists with a head (n = 297) or facial (n = 289) injury. Controls were helmeted cyclists with other injuries, excluding the neck. Participants were interviewed in seven Alberta emergency departments or by telephone; injury data were collected from charts. Missing values were imputed using chained equations and custom prediction imputation models.

Results

Compared with excellent helmet fit, those with poor fit had increased odds of head injury (odds ratio [OR] = 3.38, 95% confidence interval [CI]: 1.06–10.74). Compared with a helmet that stayed centred, those whose helmet tilted back (OR = 2.90, 95% CI: 1.54–5.47), shifted (OR = 1.91, 95% CI: 1.01–3.63) or came off (OR = 6.72, 95% CI: 2.86–15.82) had higher odds of head injury. A helmet that tilted back (OR = 4.81, 95% CI: 2.74–8.46), shifted (OR = 1.83, 95% CI: 1.04–3.19) or came off (OR = 3.31, 95% CI: 1.24–8.85) also increased the odds of facial injury.

Conclusion

Our findings have implications for consumer and retail education programs.
Prévalence de l'hystérectomie autodéclarée chez les Canadiennes, 2000-2001 à 2008
Authors: Stankiewicz A , Pogany L , Popadiuk C
Published: October 2020

Introduction

L'hystérectomie est l'une des interventions chirurgicales les plus souvent pratiquées chez les Canadiennes. Le dépistage du cancer du col de l'utérus n'est donc plus nécessaire dans cette population. Notre analyse visait à obtenir des estimations plus exactes de la participation au dépistage du cancer du col utérin dans la population admissible en déterminant la prévalence de l'hystérectomie selon l'âge chez les Canadiennes de 20 à 69 ans, par province ou territoire, entre 2000-2001 et 2008.

Méthodologie

Les données relatives à la prévalence de l'hystérectomie autodéclarée ont été tirées de l'Enquête sur la santé dans les collectivités canadiennes de 2000-2001, de 2003 et de 2008. Nous avons estimé la prévalence selon l'âge et les intervalles de confiance (IC) à 95 % pour le Canada et les provinces et territoires pour les trois périodes.

Résultats

Des variations interprovinciales de la prévalence de l'hystérectomie ont été observées chez les femmes dans chaque groupe d'âge et au cours de chaque période. Chez les femmes de 50 à 59 ans, la prévalence a semblé diminuer dans toutes les provinces entre 2000-2001 et 2008, le plus haut taux provincial atteint en 2008 étant 35,1 % (IC à 95 % : 25,8 à 44,3; p $lt; 0,01).

Conclusion

Les variations selon les provinces et au cours du temps laissent penser qu'il pourrait être bon d'utiliser la prévalence de l'hystérectomie pour ajuster la population admissible au dépistage du cancer du col de l'utérus, de manière à obtenir des taux plus comparables de participation. Il est en outre possible d'ajuster à la fois les taux d'incidence du cancer du col utérin et de mortalité par cancer du col utérin de façon à ce que les estimations dans le temps et pour l'ensemble des provinces et territoires soient comparables.

Published: October 2020

Introduction

Au fur et à mesure du vieillissement de la population et de l'augmentation de la prévalence d'affections concomitantes, le recours à des méthodes fiables et efficaces de surveillance des affections concomitantes de maladies chroniques telles que la sclérose en plaques (SP) s'avère de plus en plus nécessaire.

Méthodologie

Nous avons évalué, au moyen de la statistique kappa (k), la performance des définitions administratives de cas pour les affections concomitantes fréquemment observées en lien avec la SP en comparant les concordances entre les données administratives et les données provenant d'autodéclarations au Manitoba (MB) (n = 606) et en Nouvelle-Écosse (NS) (n = 1 923).

Résultats

Les concordances entre les définitions administratives et les autodéclarations étaient bonnes pour l'hypertension (k = 0,69 [NS] et 0,76 [MB]) et le diabète (k = 0,70 [NS] et 0,66 [MB]), modérées pour l'hyperlipidémie (k = 0,53 [NS] et 0,51 [MB]) et la cardiopathie (k = 0,42 [NS] et 0,51 [MB]) et médiocres pour l'anxiété (k = 0,27 [NS] et 0,26 [MB]). La concordance était bonne en Nouvelle-Écosse pour la maladie inflammatoire chronique de l'intestin (k = 0,71) et modérée pour l'épilepsie (k = 0,48).

Conclusion

Les définitions administratives étaient performantes dans les deux provinces pour plusieurs affections concomitantes fréquemment observées en lien avec la SP. À la lumière de ces résultats, il semble que ces définitions puissent être utilisées plus largement au Canada et dans les études nationales.
Épidémiologie de la rhinite allergique au Québec d'après une enquête populationnelle de 2008
Authors: Canuel M , Lebel G
Published: October 2020

Introduction

Notre étude avait pour objectif d'estimer la prévalence des symptômes et du diagnostic médical de la rhinite allergique (RA) chez les personnes âgées de 15 ans et plus au Québec.

Méthodologie

L'Enquête québécoise sur la santé de la population de 2008 a fourni les données de la prévalence des symptômes de RA et de la proportion de RA diagnostiquée par un médecin au cours de la vie. La prévalence des symptômes a été définie comme la proportion d'individus qui, en l'absence de rhume ou de grippe, ont eu des symptômes nasaux et oculaires au cours des 12 mois précédant l'enquête.

Résultats

La prévalence des symptômes de RA a été estimée à 17 %, dont 9 % de personnes n'ayant pas reçu de diagnostic. La RA était moins fréquente chez les répondants de 65 ans et plus (12 %) et elle était plus répandue chez les femmes (19 %) que chez les hommes (15 %). La proportion de RA diagnostiquée par un médecin au cours de la vie a été estimée à 17 %.

Conclusion

La RA est fréquente au Québec. En effet, environ une personne sur six en éprouve les symptômes. Cette maladie est sous-diagnostiquée et sans doute aussi sous-traitée.
Communication courte - Le rôle de l'insuline d'origine animale dans le traitement du diabète de type 1 et sa disponibilité
Authors: Klein AV , Taylor E , Legaré C , Vu D , Griffiths E
Published: October 2020

En raison d'un certain nombre de facteurs, on traite désormais davantage le diabète insulinodépendant au moyen de préparations d'insuline recombinante (biosynthétique) qu'au moyen d'insuline d'origine bovine et porcine. Cependant, certaines personnes atteintes du diabète de type 1 parviennent à mieux prendre leur diabète en charge à l'aide d'insuline d'origine animale. Malgré la disponibilité de plus en plus réduite de l'insuline d'origine animale et le déclin de sa production, on peut encore s'en procurer sur le marché canadien, en particulier l'insuline porcine.
Cette communication décrit les mesures prises par Santé Canada relativement à la disponibilité de l'insuline d'origine animale.
Grappes de multimorbidité chez les Autochtones et chez les non-Autochtones d'origine blanche au Canada
Authors: Kuwornu JP , Lix LM , Shooshtari S
Published: October 2020

Introduction

Les profils de multimorbidité, c'est-à-dire la présence concomitante de deux maladies chroniques ou plus, ne sont pas nécessairement constants d'une population à l'autre. Les objectifs de notre étude étaient de comparer les estimations relatives à la prévalence de la multimorbidité entre une population canadienne autochtone et une population appariée non autochtone d'origine blanche et de définir les grappes de maladies chroniques caractérisant ces deux groupes.

Méthodologie

Nous avons utilisé les données de l'Enquête sur la santé dans les collectivités canadiennes (ESCC) pour cibler les répondants adultes (18 ans et plus) ayant déclaré être d'origine autochtone ou d'origine non autochtone blanche et être atteints d'au moins 2 des 15 maladies chroniques les plus fréquentes visées par l'ESCC. Les Autochtones répondant à ces critères ont été appariés en fonction du sexe et de l'âge à des non-Autochtones d'origine blanche. Les analyses ont été stratifiées par âge (18 à 54 ans, 55 ans et plus). Nous avons estimé la prévalence en utilisant la pondération employée dans l'enquête. Nous avons procédé à une analyse de structure latente (ASL) pour définir les grappes de maladies.

Résultats

Nous avons apparié 1 642 répondants autochtones au même nombre de répondants non autochtones d'origine blanche. Sur l'ensemble, 38,9 % (IC à 95 %: 36,5 % à 41,3 %) des Autochtones étaient atteints de deux maladies chroniques ou plus, contre 30,7 % (IC à 95 %: 28,9 % à 32,6 %) des non-Autochtones. La comparaison des résultats de l'ASL a révélé que le meilleur ajustement aux données était obtenu avec trois grappes ou avec quatre grappes. Alors que les maladies concomitantes qui se manifestaient chez les personnes les plus âgées des deux populations avaient tendance à être similaires, les groupes plus jeunes de ces deux populations présentaient des différences.

Conclusion

Un petit groupe de répondants autochtones dans le groupe des plus jeunes présentait un profil complexe de maladies chroniques concomitantes. Ces personnes tireraient sans doute grand profit de programmes de gestion des maladies.

The Influence of the Cuboid Float’s Parameters on the Stability of a Floating Building
Authors: Karczewski Artur , Piątek Łukasz
Published: October 2020

Usually, the concept of sufficient stability of a floating structure is connected with the capacity to keep a small heel angle despite the moment of heeling. The variable responsible for these characteristics is the initial metacentric height, which is the relation between the hydrostatic features of the pontoon and the mass properties of the entire object. This article answers the questions of how heavy the floating system should be, what the minimum acceptable draft is, and whether it is beneficial to use internal fixed ballast. To cover various technologies, a theoretical model of a cuboid float with average density representing different construction materials was analysed. The results indicate that the common practice of using heavy and deep floating systems is not always reasonable. In the case of floating buildings, which, unlike ships, can be exploited only under small heel angles, the shape and width of the submerged part of the object may influence the stability more than the weight or draft.
Application of Shape Memory Alloys in Pipeline Couplings for Shipbuilding
Authors: Matuszewski Leszek
Published: October 2020

The aim of the study is to analyse shape memory alloy (SMA) pipeline joints in limited space applications for all kinds of ships. Generally, the space available in various areas on ships is strictly limited and service works usually meet many obstacles. If we consider a pipeline, the flange joints always require a larger free space around the pipe than the pipe alone. A simultaneous problem can occur with the propeller shaft line coupling between bearings. SMA couplings require less space around the pipe and service should be easier, e.g., insulation fixing, painting and so on. SMA couplings last for a lifetime and there is no need for periodical seal replacement. Herein, some proposals among other unpublished data are discussed. There is a significant technological interest in the use of SMAs for applications not widely used yet. A wide variety of alloys present the shape memory effect and many generate an expressive restitution force considerable for commercial interests.

Authors: Woloszyk Krzysztof , Garbatov Yordan
Published: October 2020

The objective of this work is to investigate the structural compressive response of plates with locked cracks accounting for all relevant factors and correlation between them. The nonlinear FE model considering both geometric and material nonlinearities is employed herein, and the FE model of the structural response of intact plates is validated with the available experimental data. In the common studies, based on One Factor at a Time analysis, some of the parameters and interactions between them are excluded. In the present study, the numerical investigations are conducted with the use of the Design of Experiments techniques, where all essential parameters and their interactions are adequately considered. With a total of 32 numerical analyses, the most influential factors and their interactions are identified. As a study outcome, empirical formulations, which allow for a fast estimation of the ultimate compressive strength of intact plates, plates with locked cracks, and repaired cracked plates, are derived. The developed formulations represent a fast and practical tool for estimating the ultimate compressive strength of intact, cracked, and repaired plates, which can be easily employed in the reliability analysis.results followed by their discussion.
Hydrodynamic Model of the New Waterway Through the Vistula Spit
Authors: Szydłowski Michał , Kolerski Tomasz
Published: October 2020

The decision to build a new waterway (strait) in the Polish part of the Vistula Spit was made in 2017. The new connection between the Gulf of Gdańsk and the Vistula Lagoon is planned as an artificial navigable channel with a lock and a small port. During storm surges and wind tides in the gulf or in the lagoon, sluicing will be required for vessels to tackle the Vistula Spit. This procedure does not require significant water flow through the channel in normal conditions. However, in the case of a lock failure or in the case of controlled opening of the gate to increase water exchange in the lagoon or to reduce flood risk in the Vistula Lagoon, high flow rates may occur in the navigable channel and in the neighboring port basin. In order to inves-tigate the hydraulic conditions in such extraordinary situations, numerical modeling of the hydrodynamics during water damming in the gulf or in the lagoon is performed. To analyze the hydrodynamics of the artificial connection between the sea and the lagoon during periods of high water stages, mathematical modeling is required. This paper presents the shallow water equations (SWE) model adapted to simulate the flow through the port basin and the navigable channel. The calcula-tions allowed the relation between the water head and the capacity of the navigable channel to be found, as well as to analyze circulations which may occur in the port basin.

Published: October 2020

Sodium is an essential mineral, necessary for optimal development of an infant. However, its content in human milk is highly variable. The main factors influencing sodium content in human milk are the concentration of other osmoles (dominantly lactose) and time postpartum. It is still debatable if maternal sodium intake affects sodium content in human milk. Overall, Latvian inhabitants consume more sodium than recommended. Therefore, we aimed to analyse the relation between maternal sodium intake and human milk sodium content. In total, 64 human milk samples and food data from 64 participants were obtained. Sodium content was determined using inductively coupled plasma mass spectrometry. Food diary data was analysed using Finnish database Fineli. The results showed that median sodium content in human milk was 12.67 mg per 100 ml−1. Nevertheless, large inter-individual differences were observed (5.00–42.54 mg·100 ml−1). Sodium in-take among the participants was higher than the recommended 2000 mg per day (median intake — 2335.83 mg per day). Although a positive association was found between median maternal sodium intake and sodium content in human milk (ρ= 0.350, p = 0.010), a hierarchical multiple regression revealed that only infant’s age was a significant factor (p = 0.038), explaining 13% of the variability of sodium content in human milk. Sodium content in human milk is not influenced directly by maternal sodium intake, and other factors (such as lactose and potassium concentration in human milk not considered in the study) could potentially influence sodium content in human milk.

Authors: Zatybekov Alibek , Turuspekov Yerlan , Doszhanova Botakoz , Didorenko Svetlana , Abugalieva Saule
Published: October 2020

Soybean is increasingly becoming one of the main oilseeds crops in Kazakhstan, with a major growing area in the south-eastern part of the country. The comparative assessment of small-size (108) and medium-size (276 accessions) collections of soybean originated from five regions of the world was made in field trials in Almaty region (south-east of Kazakhstan). The full collection was genotyped using the Illumina iSelect 6K SNP (single nucleotide polymorphism) array that allowed observation of 4651 polymorphic SNPs. The genome-wide association study (GWAS) was conducted using the following six important agronomic traits: flowering time, seed maturation time, plant height, number of fertile nodes, number of seeds per node, and thousand seed weight. In total, GWAS using TASSEL package identified 56 stable QTNs (quantitative trait nucleotdies) for all the studied traits, including 42 QTNs detected using the medium-size collection. It was shown that the medium-size population, in comparison with the small-size population, was preferable for the detection of significant associations. A comparative analysis of the data with previously published results suggested that 36 of the stable 56 QTNs were presumably novel associations. The revealed QTNs can be used in the molecular breeding projects for soybean yield improvement.

Authors: Hasanov Ilman , Abbasov Ibrahim , Gurbanov Nurlan
Published: October 2020

Currently, various variants of physical and geometrical non-linear calculation of anisotropic bodies have been developed. In spite of the large and increasing number of studies on the theory of shells there are still many unsufficiently developed problems important both in scientific and applied fields, for example, development of practically convenient methods for calculating of anisotropic sealing composite materials weakened by eccentric holes under the influence of local loadings. Stress-deformed state of a packing ring with eccentric holes of sealing materials was studied. In composite materials, the Hooke’s equation was used for this purpose. Also, using Lurie’s symbolic method, the concrete solution of the sealing problem with eccentric holes was obtained.

Authors: Stanke Agija , Kampars Valdis , Lazdovica Kristine
Published: October 2020

In this study mesoporous SBA-15 was synthesized under acidic conditions using triblock copolymer Pluronic P123 as template and tetraethyl orthosilicate as a silica source. SBA-15 was modified by different iron loading (1.8 %, 5 % and 10 %) via post-synthesis impregnation with Fe(NO3)3·9H2O. The obtained catalysts were characterized using XRD analysis, WDXRF spectroscopy and N2 adsorption-desorption analysis. Pyrolysis of cellulose with and without the catalyst was investigated using TG-FTIR. It was found that the presence of the synthesized catalysts affects formation of solid residue and significantly alters the composition of the other pyrolysis products. All catalysts considerably reduced the fraction of compounds containing hydroxyl group. Fe (10 %)/SBA-15 exhibited the highest deoxygenation ability. SBA-15 showed the highest catalytic selectivity for synthesis of olefins, while Fe (1.8 %)/SBA-15 showed the highest catalytic selectivity for synthesis of aromatic hydrocarbons.
Potential of Chlorella Species as Feedstock for Bioenergy Production: A Review
Authors: Ievina Baiba , Romagnoli Francesco
Published: October 2020

Selection of appropriate microalgae strain for cultivation is essential for overall success of large-scale biomass production under particular environmental and climate conditions. In addition to fast growth rate and biomass productivity, the species ability to grow in wastewater must also be considered to increase the economic feasibility of microalgae for bioenergy purposes. Furthermore, the content of bioactive compounds in a strain must be taken into account to further increase the viability by integration of biorefinery concept. Chlorella spp. are among the most studied microalgal species. The present review attempts to unfold the potential of species of the genus Chlorella for bioenergy production integrating applicability for wastewater treatment and production of high added-value compounds. Several key features potentially make Chlorella spp. highly beneficial for bioenergy production. Fast growth rate, low nutritional requirements, low sensitivity to contamination, adaptation to fluctuating environments, ability to grow in photoautotrophic, heterotrophic and mixotrophic conditions make Chlorella spp. highly useful for outdoor cultivation coupled with wastewater treatment. Chlorella is a source of multiple bioactive compounds. Most promising high-value products are chlorophylls, lutein, β-carotene and lipids. Here we demonstrate that although many Chlorella spp. show similar characteristics, some substantial differences in growth and response to environmental factors exist.

Published: October 2020

The paper displays results of the questionnaire called “Particulate matter pollution in air”, which serves as a tool to determine level of public awareness of the health risks related to pollution from small capacity heating equipment in households. Barriers for installation of the innovative flue gas treatment technology called a fog unit in households and possible mechanisms to decrease or prevent these barriers were defined. The first part of the questionnaire included overall information about participants: age, gender, education level, place of residence, activities to protect the environment and motives behind performing these activities. The remaining questions were divided in four groups: “Environmental views”, “Knowledge on air pollution”, “Willingness to pay”, “Choice of flue gas treatment technologies”. The results of questionnaire correspond with raised problem situations. Over 80 % of respondents lack information on pollution and possible consequences deriving from it, and on potential solutions to prevent pollution. Residents of households are willing to pay for installation of flue gas treatment equipment (capital investments).

Published: October 2020

Nowadays the transport sector is one of the most challenging sectors in terms of reducing pollution produced in this sector. It becomes more and more clear that one of the best solutions for mitigating this pollution and the climate change linked to it is the usage of electrified railway. The aim of this article is to evaluate the impact that electrification of the railway will have on the environment from the perspective of pollution. The article shows a system dynamics model, which is based upon factors that affect a newly electrified railway. These include power demand, economics and the environmental impact originating from the railway. This model can be applicable for any country, however in this article Latvia is modelled as an example of how the model works and how the environmental factors will change as a result of an electrification of Latvia’ s railway system.
Speaking to My Ancestors: An Ethnographic Study of Lived Childhood Religion in Rural Gansu
Authors: Chadwin Joseph
Published: October 2020

This article provides an overview of the major existing scholarship pertaining to childhood religion in the People’s Republic of China (PRC). More specifically, it examines lived childhood religion in a rural village in Gānsù province. This article challenges the commonly preconceived notion that children in the PRC do not regard religious belief as important and simply mirror the religious practices of their guardians. By utilising ethnographic data, I argue that children in the PRC are capable of constructing their own unique form of lived religion that is informed by, but crucially distinct from, the religious beliefs and practices of adults. The practices and beliefs of this lived religion can be extremely important to children and the evidence from fieldwork suggests that they tend to take both their practice and belief very seriously.

Authors: Lanchakov A.B. , Filin S.A. , Yakushev A.Zh.
Published: October 2020

Subject. The article analyzes the expected effect of a portfolio of projects in the face of risk and uncertainty, when using real options.
Objectives. The purpose is to offer a more objective formula to assess the expected impact of a portfolio of projects for real investment objects under risk and uncertainty, using real options, and provide recommendations for improving the portfolio efficiency.
Methods. The study draws on methods of real options and evaluation of investment projects through the real option value, the cash flow discounting method, synthesis, and mathematical modeling.
Results. We systematized the main types of real options and developed a formula for calculating the expected effect of project portfolio implementation. The said formula shows that considering the additional long-term costs embedded in a portfolio of real options, which are associated with the use of these real options, and, therefore, reducing the overall risk of projects and the entire portfolio, permit to improve the objectivity of such calculations.
Conclusions. When analyzing real options that have real assets as underlying instruments, it is often impossible to apply the computational formulae for financial options, as they differ significantly. The systematization of the main types of real options helps expand the range of application of management solutions. The offered formula enables to improve the efficiency of project insurance under risk and uncertainty and to use additional opportunities for effective development of the company.

Published: October 2020

Subject. We identify the signs of manipulating the financial statements in the construction sector organizations. Objectives. We focus on developing the analytical procedures to detect the signs of financial statements manipulation, namely, the so-called window dressing. Methods. The methodological basis rests on general scientific principles and methods of research, like abstraction, generalization of approaches of domestic and foreign authors to the detection of manipulation of reporting, and statistical methods of information processing. Results. We developed a classification of methods for manipulation of unsound improvement of financial statements, assessed the likelihood of misstatement of financial statements, identified the elements of poor quality items, proposed a method to detect the manipulation of reporting, based on the comparison of substandard financial statement items with reliable items and/or non-financial indicators. We tested the methodology on the data of enterprises, operating in the construction sector. Conclusions. The study found that a likely manipulator is, usually, a micro-enterprise or a small company that does not have a credit limit, has significant relative performance of assets and liabilities of low quality, while showing high productivity and high return on assets at the average level of capital/labor ratio, and characterized by low investment and financial activity.

Published: October 2020

Subject. The article addresses the technology and trends in the digitization of public and municipal administration, and the correspondence of strategic goals of territorial development to the State and municipal policy on introducing and using digital technologies as tools to achieve these goals.
Objectives. The aim is to determine prospects for the development of digital technologies that are demanded and applied in the system of the State and municipal administration, based on the results of auditing authorities, including the analysis of the use of budget funds for acquisition (development) and support to information systems in the work of government authorities.
Methods. The methodological framework rests on traditional methods of logical, historical, comparative analysis, and on methods applied by expert services of control authorities, like the documentary method, analysis of regulations, observation and processing of collected empirical data, graphic and table analysis.
Results. We revealed and systematized problems related to the introduction and development of digital technologies in public and municipal administration, presented the composition of information systems that ensure the process of digital transformation in the sphere of governance. We built a model of digital transformation of the system of public and municipal administration, based on the systems, large-scale and innovative approaches to the management of complex deterministic systems with clear institutional boundaries and transformation goals.
Conclusions. Local governments need to work towards the quality of information systems and their data to fully incorporate them into the national system of government, to improve the digital literacy of the population.
A structural-functional model of cross-border logistics as a process subsystem of company's foreign trade activity tetrad
Authors: Oleinik S.P.
Published: October 2020

Subject. To assess the potential of corporate management of company’s foreign trade activities, the article considers the structure and functionality of its constituent systems and, particularly, the cross-border logistics as a process subsystem, are of interest nowadays.
Objectives. Based on the main provisions of the theory of system economics, the study aims to build a structural and functional model of cross-border logistics, which is a process subsystem of the tetrad of company's foreign trade activities.
Methods. The study draws on the systems approach, methods of analysis and synthesis, grouping and comparison, abstraction, generalization, analogies, logical analysis, and the management theory elements.
Results. I built a structural and functional model of cross-border logistics as a subsystem of the tetrad of company's foreign trade activity, which meets the previously formulated conditions for model verification. The paper particularizes the systems of four types of basic typology and substantiates their inclusion in the process subsystem; discloses the essence of general economic processes implemented by each system, and determines the content of produced and consumed goods. I developed a model of interaction between administrative (customs regulation) and corporate (cross-border logistics) tetrads.
Conclusions. The model enables to identify four systems that due to their functionality are responsible for movement of goods across the customs border, and to describe this process from the perspective of space-time approach. The movement of goods across the customs border is determined by the interaction of administrative and corporate tetrads, and the key factor is the activity of process subsystems.

Policy formation and implementation have largely shifted from a top-down government-led process, to a collaborative governance approach characterised by complex and opaque partnerships, weakly steered by the state.  We use 36 interviews, undertaken in Toronto and Melbourne between 2015 and 2018, to assess procedural accountability in these two cities: the extent to which policy outputs developed through a partnership approach are fair, transparent, rational, and intentional.  We find that both cities fail the basics of procedural accountability, and that there is little shared understanding amongst key partners – local and provincial/state policymakers, non-profit and private sector housing providers, and philanthropic and private sector finance providers – about the definition and missing quantum of affordable housing, let alone a sense of how to move forward.
Exploring the Federal Role in Protecting Canada’s Farmland: A Matter Worthy of National Interest?
Authors: Connell David J
Published: October 2020

Is protecting farmland a matter of national interest?  If so, should the federal government play a stronger role in agricultural land use planning (AgLUP)?  This paper examines potential roles and contributions of the federal government in AgLUP.  Methods were based on surveys with key informants that examined the validity and viability of six possible roles of the federal government.  The key informants were provincial-level experts in AgLUP from across Canada.  We found that all six of the potential roles of the federal government to protect farmland that we identified are, to varying degrees, valid and reliable options.  Two of the six roles were viewed most favourably: co-operative federalism; integrated policy approach.  We also identified a seventh role, which is for the federal government to adopt a policy that ensures that decisions regarding the use of federal-owned land must adhere to provincial legislation.

Seventy nine of hotel managers were interviewed based on cluster sampling method to gain their point of view. The results show that destination must build their images around unique attributes that provide them sustainable competitive advantage including its attraction which should be designed to meet the needs of the target market and should be served by local products. The results also show that hotel managers thought that foreign tourists always preferred imported products, meanwhile previous statistical results indicate that foreign tourists significantly look for local products. There is a need to encourage hotel managers to change their perception and attitude about local and imported products. In fact, hoteliers expressed willingness to use local products as long as these meet the quality standard. As tourism involves four types of activities, namely something to see, something to do, something to buy, something to learn, destination product development could be focused in the above activities through offering foreign tourist, such as to stay in hotels, homestays or villas owned by Balinese; to eat in restaurants owned by Balinese by choosing the authentic local foods that are using local meat, seafood and vegetables, exotic local fruits and beverages; and to buy products that are produced by the Balinese. By promoting vacation on the real Balinese atmosphere such as stay in accommodations owned by the Balinese supported by the authenticity of local Balinese foods, fruits and beverages, these will strengthen the local economy, so the benefit of tourism development can be more beneficial to the local Balinese. The results suggests that destination management related to improvement of service and hospitality are really important through improvement of human resource by giving training to their employees, educate consumers, and manage consumer expectations. Physical evidence can be easily associated with the product by the customer. This includes the atmosphere of the service operation and any tangible evidence used to market the product. Marketing through authenticity is precise approach for success in destination marketing of Bali tourism. Destination marketing strategy should then be focussed on promoting the physical evidences of the authenticity of the local products and excellent services offered to the visitors as well as participation of stakeholders in developing authenticity of local products at reasonable price which will differentiate the destination distinctively.
