A Kalman filter-based hybridization model of statistical and intelligent approaches for exchange rate forecasting
Authors: Khashei Mehdi , Mahdavi Sharif Bahareh 
Published: September 2020

Purpose
The purpose of this paper is to propose a comprehensive version of a hybrid autoregressive integrated moving average (ARIMA), and artificial neural networks (ANNs) in order to yield a more general and more accurate hybrid model for exchange rates forecasting. For this purpose, the Kalman filter technique is used in the proposed model to preprocess and detect the trend of raw data. It is basically done to reduce the existing noise in the underlying data and better modeling, respectively.

Design/methodology/approach
In this paper, ARIMA models are applied to construct a new hybrid model to overcome the above-mentioned limitations of ANNs and to yield a more general and more accurate model than traditional hybrid ARIMA and ANNs models. In our proposed model, a time series is considered as a function of a linear and nonlinear component, so, in the first phase, an ARIMA model is first used to identify and magnify the existing linear structures in data. In the second phase, a multilayer perceptron is used as a nonlinear neural network to model the preprocessed data, in which the existing linear structures are identified and magnified by ARIMA and to predict the future value of time series.

Findings
In this paper, a new Kalman filter based hybrid artificial neural network and ARIMA model are proposed as an alternate forecasting technique to the traditional hybrid ARIMA/ANNs models. In the proposed model, similar to the traditional hybrid ARIMA/ANNs models, the unique strengths of ARIMA and ANN in linear and nonlinear modeling are jointly used, aiming to capture different forms of relationship in the data; especially, in complex problems that have both linear and nonlinear correlation structures. However, there are no aforementioned assumptions in the modeling process of the proposed model. Therefore, in the proposed model, in contrast to the traditional hybrid ARIMA/ANNs, it can be generally guaranteed that the performance of the proposed model will not be worse than either of their components used separately. In addition, empirical results in both weekly and daily exchange rate forecasting indicate that the proposed model can be an effective way to improve forecasting accuracy achieved by traditional hybrid ARIMA/ANNs models.

Originality/value
In the proposed model, in contrast to the traditional hybrid ARIMA/ANNs, it can be guaranteed that the performance of the proposed model will not be worse than either of the components used separately. In addition, empirical results in exchange rate forecasting indicate that the proposed model can be an effective way to improve forecasting accuracy achieved by traditional hybrid ARIMA/ANNs models. Therefore, it can be used as an appropriate alternate model for forecasting in exchange ratemarkets, especially when higher forecasting accuracy is needed.
Fostering brand–consumer interactions in social media: the role of social media uses and gratifications
Authors: Qin Yufan Sunny 
Published: September 2020

Purpose
An increasing number of brands are using algorithms to embed brand-related content to targeted consumers’ social media pages. This paper aims to analyze how do consumers’ motives of using social media in general influence their potential brand–consumer interactions and the following branding outcomes. To examine this, this study selected Facebook as the social media platform and Nike as the brand to conduct an online survey experiment to examine the effects of social media usage motives on consumers’ interactions with the brand in social media.

Design/methodology/approach
An online survey experiment using Nike’s Facebook page as the stimuli was conducted to analyze the interactions between consumers and a specific brand’s social media page in a natural setting. Data were collected in the USA via Amazon’s Mechanical Turk (MTurk).

Findings
This study demonstrated that brand–consumer interactions, both content-consumption and content-contribution intentions, can be fostered by certain motives of using social media: information-seeking and self-identity. This study also suggested that content-consumption behavior has significant associations with consumers’ positive attitudes toward the brand’s social media pages, while content-contribution behavior does not show significant effects.

Originality/value
This study provides new insights about how consumers’ general motives of social media usage influence their intentions to interact with the brand in social media from two levels (i.e. content-consumption and content-contribution).
The influence of corporate governance structure on sustainability reporting in Malaysia

Published: September 2020

Purpose
Following the introduction of the revised Malaysian Code on Corporate Governance in 2012 (MCCG 2012), this study aims to investigate the influence of corporate governance structure on the quality of sustainability reporting from the perspectives of agency theory and resource dependence theory.

Design/methodology/approach
Based on an analysis of 126 firms’ annual reports for the year ended 2010 and 2014, this study analyses sustainability reporting quality before the introduction of MCCG, 2012 (year ended 2010) and after (year ended 2014).

Findings
The findings of the study show that there was a significant increase in the quality of sustainability reporting from 2010 to 2014. Results from multiple regression analyses indicate that the number of sustainability-related training attended by the board of directors and the percentage of directors with sustainability-related experience have a significant impact on the quality of sustainability reporting.

Practical implications
Observations from the study provide useful insights into the importance of the appointment of directors with sustainability-related experience as part of the criteria for directors’ appointment. Moreover, the board of directors is encouraged to attend sustainability-related training to help firms improve sustainability practices and reporting.

Social implications
The increase in the quality of sustainability reporting indicates that companies are committed in ensuring that environmental degradation is put at the minimum level if not eliminated. It appears that companies are embracing the concept of sustainability reporting, and hence, contributing to improving and enhancing social well-being.

Originality/value
This study contributes to the discussion of both internal mechanisms (board independence and board capital) and external mechanisms (compliance to the code on corporate governance) of corporate governance structure on the quality of sustainability reporting. The findings can be used to identify necessary mechanisms that should be enhanced to strengthen the practice of sustainability reporting.
Neonatal lupus erythematosus exacerbated by vaccination
Authors: Ishikawa Masato , Mori Tatsuhiko , Yamamoto Toshiyuki 
Published: September 2020

AbstractNeonatal lupus erythematosus (LE) is a rare immune‐mediated disease caused by placental transport of maternal anti‐SSA/Ro, anti‐SSB/La and/or anti‐U1RNP antibodies. Here, we demonstrate two cases of neonatal LE, in both of which cutaneous LE was exacerbated by inoculation. To our knowledge, cases worsening neonatal LE after administration of vaccines have not been reported. In case 1, not only exacerbation of pre‐existing annular erythema but also spreading of new erythematous lesions to the trunk and extremities were induced following vaccination. Of interest, all of the lesions simultaneously improved. By contrast, in case 2, pre‐existing facial erythema became prominent without spreading to other sites. The mother of case 1 had Sjögren’s syndrome, whereas in case 2, the mother was diagnosed with Sjögren’s syndrome on this occasion for the first time. Immunohistochemistry in case 1 revealed interleukin (IL)‐17‐positive cells infiltrating into the papillary dermis, and CD123‐positive plasmacytoid dendritic cells in the papillary dermis and the deep reticular dermis. Both innate immune response and IL‐17 mediated inflammation following vaccination are speculated as a possible mechanism of the deterioration of LE lesions in our juvenile cases. Caution is necessary since neonatal LE can be worsened following vaccination.

Published: September 2020

AbstractMuch attention has been paid recently to land grabs in rural and urban areas of the global South, but relatively little attention has been paid to such activities in the third dimension—vertical space. Yet vertical space has also been increasingly colonized, as manifest in the transformation of mega‐city skylines through the proliferating number and height of high‐rises in both central cities and peri‐urban developments. We investigate how floor area ratio policies, originally designed to control densification, have been reworked to facilitate densification through floor area uplift. Thus a tool originally developed to advance public welfare has been used to facilitate the profitability of real estate projects for developers and to benefit local governments. Taking DKI Jakarta as our case study, we sketch out the coevolution of this policy with urban regimes, focusing on the mid‐2010s when compensation measures were formalized and made transparent. By using a particular project in Jakarta's central business district we show how the benefits of floor area uplift favor private sector developers over the local government. In a context of rapidly increasing land values, increasing demand for housing from an emergent middle class, and particularly the privatization of planning, this unevenness systematically favors the private sector.

AbstractQuantifying the long‐term population trajectory of species and the factors affecting these trends is a fundamental part of animal conservation. We describe the results of a long‐term investigation of temporal changes in the occurrence of arboreal marsupials in the wet eucalypt forests of south‐eastern Australia. The assemblage includes habitat specialists such as the vulnerable greater glider Petauroides volans and the critically endangered Leadbeater’s possum Gymnobelideus leadbeateri, as well as common and widespread taxa. Using data gathered between 1997 and 2018, we quantified relationships between site occupancy of four marsupial species and spatio‐temporal site and landscape‐level variables, including the number of hollow‐bearing trees at a site, and the extent of fire and logging in the surrounding landscape. We found evidence that: (1) The number of hollow‐bearing trees (which are critical den sites for arboreal marsupials) has declined substantially in the past two decades. (2) There was a decline in all species of arboreal marsupials. (3) The presence of all species of arboreal marsupials was positively linked to the number of large old hollow‐bearing trees at a site. (4) The extent of logging disturbance in the landscape surrounding a site had a positive impact on the sugar glider Petaurus breviceps but a negative effect on Leadbeater’s possum. This suggests that ongoing logging will have further negative impacts on Leadbeater’s possum. (5) The presence of the greater glider and sugar glider declined with increasing amounts of fire in the landscape. Negative fire effects are a concern as montane ash forests are increasingly susceptible to high‐severity wildfires. Stronger efforts are needed to reduce the extent and frequency of logging and fire disturbance in mountain ash forests to protect arboreal marsupial populations.

Published: September 2020

AbstractThe study aimed to determine the effect of different irrigation activation systems on the amount of apical debris extrusion in mandibular molar teeth with curved root canals. Sixty extracted mandibular molar teeth were instrumented with HyFlex EDM system and divided into four groups according to irrigation techniques: passive ultrasonic irrigation (PUI), EDDY, photon‐initiated photoacoustic streaming (PIPS) and manual irrigation (MI). After the final irrigation, the extruded irrigants were collected into Eppendorf tubes of known weights. The amount of extruded debris was obtained by subtracting the weight from the initial weight of the tube. The Kruskal–Wallis test was used for statistical analysis. EDDY caused significantly more debris extrusion than the other irrigation activation systems (P < 0.001). PUI caused less apical debris extrusion but there was no statistical difference between PUI, PIPS and MI (P > 0.05). The EDDY activation system was associated with the highest amount of debris extrusion in curved root canals.
Tiny hitchhikers and parasites: a review of Australian heterostigmatic mites (Acari: Prostigmata) associated with insects, with description of three new species
Authors: Katlav Alihan , Riegler Markus , Seeman Owen D 
Published: September 2020

AbstractHeterostigmatic mites (Heterostigmata) are highly diverse, have symbiotic associations with various insects and occur worldwide. Despite Australia's rich insect biodiversity, little is known about its heterostigmatic mites. In this study, we conducted a preliminary study on heterostigmatic mites associated with beetles in eastern Australia and found four species, of which three were new: Caraboacarus stammeri Krczal, 1959 (Caraboacaridae) and Eutarsopolipus orpheus Katlav & Seeman, sp. nov., (Podapolipidae) associated with Australian‐endemic Gnathaphanus melbournensis (Castelnau, 1867) (Carabidae); Hoplocheylus australiensis Katlav & Seeman, sp. nov., (Tarsocheylidae) phoretic on Australian‐endemic Mastachilus quaestionis (Kuwert, 1891) (Passalidae); and Pavania gazellatris Katlav & Seeman, sp. nov., (Dolichocybidae) phoretic on introduced Digitonthophagus gazella (Fabricius, 1787) (Scarabaeidae). The species of Caraboacaridae, Dolichocybidae and Tarsocheylidae are the first species records of these families in Australia. It is likely that two of the three new species are Australian endemics, while P. gazellatris may be a more recent arrival on introduced dung beetles, possibly arriving with imports of exotic adult dung beetles. Furthermore, we provide an overview of the heterostigmatic mite fauna of Australia that consists of less than 90 species belonging to 13 families, with representatives of all known seven superfamilies. These mites have so far been mostly reported on beetles but also on other insect orders (Blattodea, Diptera, Hemiptera, Hymenoptera, Orthoptera, Thysanoptera). Our findings of three new species and one new record based on the analysis of a relatively small number of specimens and beetle species suggest that more comprehensive studies of host insect taxa will reveal a substantially larger Australian diversity of heterostigmatic mites.
Ordinary Geographies: Care, Violence, and Agrarian Extractivism in “Post‐Conflict” Colombia
Authors: Berman‐Arévalo Eloísa , Ojeda Diana 
Published: September 2020

AbstractIn Colombia’s agrarian spaces, war and extractivism are deeply entangled. Almost four years after the peace accords signed between the national government and the FARC guerrilla, post‐conflict geographies are best characterised by the ongoing dispossession of local populations related to the entrenchment of extractivism. Drawing from ethnographic work carried out in the Colombian Caribbean on the ordinary practices and spaces of social reproduction, the ordinary geographies, this article explores gendered practices of care and their role in both sustaining and disrupting paramilitary violence and agrarian extractivism. The focus not just on the gendered effects of war and extractivism, but on gender’s constitutive role in the configuration of these processes and dynamics, allows us to contribute to recent literature on extractivism, dispossession and violence from a feminist standpoint.
Inadequate iodine intake in lactating women in Sweden: A pilot 1‐year, prospective, observational study
Authors: Manousou Sofia , Augustin Hanna , Eggertsen Robert , Hulthén Lena , Filipsson Nyström Helena 
Published: September 2020

AbstractIntroductionBreastfed infants depend on breast‐milk iodine for growth and brain development, as iodine is a trace element important for thyroid hormone production. Iodine need is higher during lactation; hence, mothers and children are at risk of iodine deficiency. We aimed to explore maternal iodine and thyroidal status during lactation.Material and methodsPregnant women were recruited in Gothenburg, southwest Sweden. Maternal urine and serum were collected at pregnancy week 35‐37 (n = 84) and 0.5, 4, and 12 months postpartum. Seventy mothers provided breast milk at 0.5 months.ResultsMedian (interquartile range) breast‐milk iodine concentration was 90 (66‐116) μg/L. About 58% had breast‐milk iodine concentration <100 μg/L. Iodine supplement users (n = 13) had higher breast‐milk iodine concentration than non‐users (n = 49) (140 μg/L vs 71 μg/L, P = .001). Exclusively breastfeeding women at 4 months postpartum (n = 57) had lower median urinary iodine concentration (85 μg/L vs 133 μg/L, P = .004) and higher thyroglobulin serum concentration (22.3 μg/L vs 11.8 μg/L, P = .032) than non‐exclusively breastfeeding women (n = 25). Concentrations of thyroid hormones were unaffected.ConclusionsThis pilot study suggests that lactating women in southwest Sweden present mildly inadequate iodine intake, mainly among non‐iodine supplement users and exclusively breastfeeding mothers. Studies on the coverage of the iodine fortification program in breastfeeding women are warranted.
Transformations and Transfer: Preschool Children Understand Abstract Relations and Reason Analogically in a Causal Task
Authors: Goddu Mariel K. , Lombrozo Tania , Gopnik Alison 
Published: September 2020

Previous research suggests that preschoolers struggle with understanding abstract relations and withreasoning by analogy. Four experiments find, in contrast, that 3‐ and 4‐year‐olds (N = 168) are surprisingly adept at relational and analogical reasoning within acausalcontext. In earlier studies preschoolers routinely favored images that share thematic or perceptual commonalities with a target image (object matches) over choices that match the target along abstract relations (relational matches). The present studies embed such choice tasks within a cause‐and‐effect framework. Without causal framing, preschoolers strongly favor object matches, replicating the results of previous studies. Butwithcausal framing, preschoolers succeed at analogical transfer (i.e., choose relational matches). These findings suggest that causal framing facilitates early analogical reasoning.
Peri‐implant defect grafting with autogenous bone or bone graft material in immediate implant placement in molar extraction sites—1‐ to 3‐year results of a prospective randomized study

Published: September 2020

AbstractObjectivesTo evaluate the survival rate, the orobuccal bone resorption and stability of peri‐implant hard and soft tissues following immediate implant placement of wide diameter implants in molar extraction sites and peri‐implant defect grafting with autogenous bone (AB) or biphasic bone graft material (BBGM) with 1‐ to 3‐year follow‐up examinations.Material and MethodsFifty wide diameter implants were placed in 50 patients immediately into molar extraction sockets by a flapless approach. Peri‐implant defect augmentation was performed randomized with either AB or BBGM. Primary outcome variable was implant survival. Marginal bone level changes, orobuccal width of the alveolar crest, probing depths, and implant success were considered as secondary parameters.ResultsOne implant of the BBGM group was lost, 1 patient withdrew from the study (drop‐out). The remaining 48 patients were still in function at a follow‐up period up to 31 months after implant insertion. Interproximal marginal bone level regenerated from −7.5 mm to the level of the implant shoulder (AB + 0.38 mm, BBGM + 0.1 mm) at final follow‐up. The width of the alveolar crest changed by −0.08 mm (AB) and +0.72 mm (BBGM) at 1 mm, −0.36 mm (AB) and +0.27 mm (BBGM) at 3 mm, −0.36 mm (AB) and +0.31 mm (BBGM) at 6 mm apical to implant shoulder level. Success rate was 87.5% in the AB and 56.3% in the BBGM group (p = .058).ConclusionsMedium‐term results prove a high survival rate, a favorable amount of bone generation in both groups and a low amount of orobuccal resorption in immediate molar implant insertion.

Published: September 2020

AbstractAimsThe aim of this prospective, clinical study was to evaluate the clinical performance and histological outcome of a new equine hydroxyapatite collagenated bone block (eHAC) for horizontal bone grafting prior to implant placement.Materials and MethodsFive patients (two male/three female) with a mean age of 51.6 years (range 22–66 years) and a reduced horizontal bone width of the alveolar ridge (mean 3.5 mm) underwent horizontal bone grafting using eHAC at 10 grafting sites. Reentry was performed 6.9 months after the horizontal grafting procedure. Clinical follow‐up (mean 28.9 month) considered width gain of the alveolar ridge, soft tissue healing, and complications. To evaluate graft incorporation, four additional patients underwent histological assessment of equine blocks adjacent to autologous blocks 3 and 6 months after grafting.ResultsThe study was terminated after graft failure was observed in four of five patients. Mean horizontal bone width had increased by 3.6 ± 1.22 mm. Three out of nine implants placed had to be removed due to graft failure. Histological evaluation revealed large amounts of soft connective tissue within the grafts (mean 67.3 ± 9.5%). The proportion of new bone formation 3 months after the lateral grafting procedure revealed an average of 8.6%, compared to 11.4% after 6 to 7 months.ConclusionLateral ridge grafting using eHAC achieved measurable horizontal width gain but revealed high rates of severe complications.Clinical ImplicationsWithin the limitations of this study, eHAC bone blocks cannot be recommended for horizontal bone grafting.
