The Impact of Hedonic Shopping Value and Shopping Lifestyle on Impulsive Buying Mediated by Positive Emotion among Online Marketplace Users in Pekanbaru

This study examined the influence of hedonic shopping value and shopping lifestyle on impulsive buying among online marketplace users in Pekanbaru, Indonesia. The study used path analysis to analyse data from 112 respondents and found that hedonic shopping value had no significant effect on impulsive buying, while shopping lifestyle had a positive and significant relationship with impulsive buying. Additionally, hedonic shopping value had a positive and significant effect on positive emotions. The results suggest that to decrease impulsive buying, it is important to focus on creating a positive shopping experience and consider the shopping lifestyle of consumers
Biospeckle Laser On Clouds, a digital gateway aiming at collaborative research improvement

The Dynamic Laser Speckle (DLS) is a photonic phenomenon transformed into a technique to monitor tiny changes in many materials, particularly in biological ones (Biospeckle Laser – BSL). Its high sensitivity is key to monitor tiny changes in the tissues that can characterise biological features in medical and in agricultural samples. This work aimed to develop an environment at the world-wide-web to share raw data of BSL and to offer access to an interactively online analysis with tutorials. The gateway designed was implemented using PHP and JavaScript tools solving the challenges of managing data (images) and online interactive use. The result was an easy-to-use environment boosting the BSL research. The early results presented thousands of accesses and of more than one hundred different users from all around the world.
Mobility and Translocation of Heavy Metals from Mine Tailings in Three Plant Species after Amendment with Compost and Biosurfactant

An experiment was performed to determine the effects of mine tailings alone mixed with compost or with compost plus crude biosurfactant on the accumulation of heavy metals (Pb, Zn, Cu, Cr, Cd, and Ni) in Acacia retinodes, Nicotiana glauca, and Echinochloa polystachya. The plants were grown in soil, mine tailings, and mine tailings containing compost over a period of seven and five months for shrubs or grass, respectively. The plants Acacia retinodes and Nicotiana glauca grown in mine tailings containing compost showed increases in dry biomass (from 62 to 79%) compared with plants in only tailings. Heavy metals accumulated in the roots and leaves showed high translocation rates of Cr in N. glauca, Cd in A. retinodes, and Ni in E. polystachya. Concentrations of heavy metals in the three plants irrigated with crude biosurfactant were not significantly different from those irrigated with water. Zn and Cd fractions within mine tailings containing compost were bound to carbonate, Pb was bound to residues, and Cu was bound to Fe-oxides. Cd had the highest mobility factor followed in order by Zn, Pb, and Cu. The elevated concentrations of Pb in roots and the low translocation rate for N. glauca and A. retinodes indicate that they are suitable for phytostabilizing Pb and Zn.
OF THE THESIS

Preterm birth The animal gut hosts a complex community of microorganism, including bacteria, fungi and viruses, referred to as the microbiome. The composition of the microbiome is influenced by an ever-expanding number of factors including antibiotics, diet, sleep, exercise and birth route. Exercise has been shown to increase the diversity of gut communities in both animals and humans- a generalized metric of good gut health. It was hypothesized that with the introduction of exercise, the microbial community composition profile of rats previously exposed to hypoxia would shift in a healthy direction. The bacterial and fungal compositions were examined in groups of rats that were exposed to hypoxia before subgroups were given access to a running wheel for voluntary exercise. DNA was extracted from cecal contents for metagenomic shotgun sequencing. This experimental setup was also repeated in rats exposed to prenatal antibiotics in order to consider the large proportion of mothers who receive a series of antibiotics before delivery. Presented here is a multivariate analysis of the bacterial and fungal compositions in the gut of rats exposed to preterm birth conditions (hypoxia and/or maternal antibiotics) to evaluate if there is measurable dysbiosis and to what extent exercise can ameliorate it. There was
V-ATPase De�ciency Aggravates Hypoxia-induced Spermatogenesis Reduction by Promoting Spermatocyte Apoptosis via the JNK/c-Jun Pathway in Mice

Spermatocyte apoptosis is the primary cause of poor outcome after hypoxia-triggered spermatogenesis reduction (HSR). The vacuolar H + -ATPase (V-ATPase) has been found to be involved in the regulation of hypoxia-induced GC-2 cells apoptosis. However, the mechanism of V-ATPase regulating spermatocyte apoptosis after HSR hasnot been well elucidated. In this study, HSRmodel was established by hypoxia exposure in vivo in V-ATPase-knockout (V-ATPase-/-) and wild-type (WT) mice to investigate theeffectof V-ATPase de�ciency on spermatocyte apoptosis. GC-2, amouse pachytene spermatocyte-derived cell line, was introduced in vitro experiments. The sperm count and spermatogenic apoptosis were recorded after 60 d of hypoxia exposure in HSR model. The apoptosis of GC-2 cells was detected by �ow cytometry and TUNEL staining. The expression of JNK/c-Jun was evaluated by RNA-seq or western blot. The expression of DR 5 and caspase-8 was evaluated by RT-qPCR and western blot. The expression of V-ATPase was determined by western blot in the presence and absence ofLenti-transcription factor EB (TFEB). C-Jun interference was used for evaluating the role of JNK in regulating the apoptosis of GC-2 cells byTUNEL and �ow cytometry. The in vivo results suggested that hypoxia induced spermatogenesis reduction and downregulation of V-ATPase. Moreover, V-ATPase de�ciency resulted in moresevere spermatogenesis reduction after hypoxia exposure. The spermatogenesis reduction was associated with exacerbation of spermatocyte apoptosis. Hypoxia down-regulated the transcription of V-ATPase through inhibiting TFEB and its nuclear translocation. The mRNA and protein expressions of V-ATPaseincreased after TFEB overexpression in GC-2 cells. Moreover, V-ATPase de�ciency enhanced JNK/c-Jun activation and related DR-apoptotic pathwayin GC-2 cells.However,inhibition of c-Jun attenuated V-ATPase deciency-induced GC-2 cells apoptosis in vitro and HSR in vivo. In conclusion, JNK/c-Jun was involved in the enhancement of V-ATPase-mediated HSR in V-ATPase -/- mice. V-ATPase de�ciency aggravates spermatocyte apoptosis, which may account forthe poor spermatogenesis outcomes of V-ATPase-/- mice. The discoveredfunction of V-ATPase modulating spermatocyte apoptosis indicates its potential therapeutic effect against HSR.
Late Quaternary paleoceanographic evolution of the Aegean Sea: planktonic foraminifera and stable isotopes

Aspects of the paleoclimatic and paleoceanographic evolution of the Aegean Sea since ~130 ka are revealed by quantitative variations in planktonic faunal assemblages, the Δ18O and Δ13C isotopic composition of benthic and planktonic foraminifera, and Mg/Ca ratios in planktonic foraminifera extracted from five 6-10-m-long piston cores. Independent sea surface temperature (SST) estimates obtained using planktonic foraminiferal transfer functions and the Mg/Ca ratios show excellent agreement, with r2 correlation coefficients of 0.92-0.95. Planktonic foraminiferal assemblages are similar, through time, across several deep basins, suggesting that major changes must have occurred in near synchroneity across the Aegean Sea. The data suggest that sapropels S3, S4, and S5 were deposited under a stratified water column during times of increased primary productivity and the development of a deep chlorophyll maximum layer. Under such conditions, oxygen advection via intermediate water flow must have been significantly reduced, in turn implying bottom water stagnation. Sapropel S1 lacks a deep phytoplankton assemblage; this faunal contrast between S1 and older sapropels indicates that S1 must have been deposited in the absence of a deep chlorophyll maximum layer. Cluster analysis shows a consistent coupling of Globigerina bulloides with Globigerinoides ruber during times of nonsapropel deposition, interpreted to require a stratified euphotic zone composed of a warm, nutrient-poor upper layer and a cooler, nutrient-rich lower layer. The covariation of these two species suggests increased river runoff that controlled the fertility and stratification of the surface waters.
Conference Abstracts

The root purpose of evaluating is to see what, i f anything, we can do better than what we are doing or have done. I t is inherently practical. This presentation contends that, despite the very practical intent of evaluation efforts in social marketing, the evaluations designed and conducted often are not useful. Social marketers should apply the kind of practical marketing research perspective and procedures to their programs that commercial marketers apply to theirs. They must make formative evaluation more strategic and even quantitative, make process evaluation more diagnostic, and make summative evaluation more relevant and timely. Evaluations of social marketing programs are most useful i f they are integrated into programs in an interactive, iterative, ongoing system. Successful evaluation provides program direction as relevant, accurate, timely, and cost effective "feedforward" and feedback on program objectives, target audiences, processes, and results. I t not only guides program improvements, but also communicates program value to outside authorities. I t is decision-driven research for consumer-based programs.
VARIABEL SOSIODEMOGRAFI DAN PENGAMBILAN KEPUTUSAN ETIS: STUDI KASUS PADA AKUNTAN PROFESIONAL DI INDONESIA SOCIODEMOGRAPHIC VARIABLES AND ETHICAL DECISION-MAKING: A SURVEY OF PROFESSIONAL ACCOUNTANTS IN INDONESIA

This study examines the role of several sociodemographic variables in the ethical decision-making process of professional accountants in Indonesia, including upbringing, religion, education, and experience. This study obtained data from 87 returned questionnaires from 395 questionnaires distributed according to the sample size calculation with the research population, namely all professional accountants who are members of the Ikatan Akuntan Indonesia (IAI). The analysis method in this study uses IBM SPSS Statistics 26 data processing software using the Kendall correlation, Kruskal-Wallis and Jonckheere Terpstra tests. The results of this study indicate that ethical decision-making differs based on upbringing (parental discipline), religion and education. Meanwhile, the experience variable is not a factor that has an important role in accountants' ethical decision-making when facing ethical dilemmas. This means that the stricter the parenting style applied, the higher the level of religious observance and the level of education a person will have a different influence on the ethical decision-making process of professional accountants. This study increase the attention of actors in
How Large is the Endowment Effect in the Risky Investment Game?

The risky investment game of Gneezy and Potters (1997) has been a popular tool used to estimate risk tolerance and myopic loss aversion. Holden and Tilahun (2021) tested and found that the simple one-shot version of this game that is attractive as a simple tool to elicit risk tolerance among respondents with limited education, produce signiﬁcant endowment eﬀects in two variants of the game where alternatively safe and risky initial monetary en-dowments are allocated. In this paper we use an alternative treatment that does not induce endowment eﬀects. This allows us to establish a benchmark to assess the relative size of the endowment eﬀects when initial safe and risky en-dowments are provided (contribution 1). While Prospect Theory could predict endowment eﬀects in the game, it fails to explain the dominance of interior choices (partial investment). We propose an alternative endowment eﬀect theory that gives predictions that are more consistent with the observed partial investment behavior (contribution 2).
FAST AND FURIOUS. A KALDORIAN ANALYSIS OF DYNAMIC INDUSTRIES

Kaldor’s first growth law claims that the growth rate of GDP is strongly fuelled by the growth rate of manufacturing. Despite the fact that the literature has demonstrated the empirical validity of this law for decades, only now a strand of research is emerging, which focuses on whether specialization in certain manufacturing sub-industries is relevant for growth. This paper examines whether specialization in high-tech manufacturing entails a growth premium in addition to the growth impulse generated by industrialization. Based on a dataset of 146 countries over the period 1971 – 2011, we find that high-tech manufacturing industries foster economic growth more so than low-and medium-tech industries. Economies of scale and technological spillovers are among the drivers identified in the literature to explain the growth enhancing effects of technology-intensive industries.
Microbial analysis of soils from avocado crops modified by different organic amendments and its role in disease suppressiveness.

In southern Spain, the most destructive root rot diseases of avocado are caused by Rosellinia necatrix and Phytophthora cinnamomi. The addition of organic amendments or mulches produced some benefits; among them, seem to prevent the disease by their influence in the microbial balance in the soil. In this sense, we are studying the effect of the application of different types of amendments to avocado trees, in order to get insight about their influence on the soil microbial communities and activities. The analysis of cultured microorganisms revealed the importance of specific groups of microorganisms in these soils, like actinomycetes or the genera Pseudomonas. The culture-independent technique DGGE revealed the presence of complex bacterial communities in the different treatment with organic mulches.
Tracking both pose and status of a traﬀic light via an Interacting Multiple Model filter

—Either for driver assistance systems or autonomous vehicles, detecting trafﬁc lights (status and pose) is required when Intelligent Transport Systems go downtown. As detection algorithms could still have some misclassiﬁcation on the trafﬁc light status, this paper proposes a solution to nearly avoid this problem. An Interacting Multiple Model ﬁlter is used to track both the position and the status of a trafﬁc light through the time and to increase trafﬁc light recognition performances for automation purpose.
Corrigendum to “A taxonomy for classifying user groups in location-based social media” published in AGILE: GIScience Series, 1, 5

Location-based social media provide great opportunities to monitor and map social, natural or health-related events. Due to the vast amount of data, it is appropriate for many researchers to use a judiciously selected sample of data. However, many of the datasets from social media sources do not consist of representative samples of the overall population because they do not take into account the users who generate the social media content. The consequences can be a bias of particular user groups and a misinterpretation of the analysis re-sults. To overcome these shortcomings, this paper develops a taxonomy of user groups in social media based on a thorough literature analysis. The different approaches can be summarized to the five dimensions: character, connectivity, communication, content and coordinates. The expected use of the taxonomy is to support the selection of social media datasets by choosing only those user groups that provide relevant information and to improve the analysis by identifying significant groups. Both application areas are illustrated by using a dataset that includes the members of the German parliament who registered on Twitter.
Movement initiation and grasp representation in premotor and 1 primary motor cortex mirror neurons 2

23 Pyramidal tract neurons (PTNs) within macaque rostral ventral premotor cortex (F5) and primary 24 motor cortex (M1) provide direct input to spinal circuitry and are critical for skilled movement control, 25 but surprisingly, can also be active during passive action observation. We recorded from single neurons, 26 including identiﬁed PTNs in the hand and arm area of primary motor cortex (M1) (n=189), and in 27 premotor area F5 (n=115) of two adult male macaques, while they executed, observed, or simply 28 withheld (NoGo) reach-to-grasp and hold actions. We found that F5 maintains a more sustained, 29 similar representation of grasping actions during both execution and observation. In contrast, although 30 some M1 neurons mirrored during the grasp and hold, M1 population activity during observation 31 contained signatures of a withholding state. This suggests that M1 and its output may dissociates 32 signals required for the initiation of movement from those associated with the representation of grasp 33 in order to ﬂexibly guide behaviour. 34
Modelling Inhomogeneous Geodata Quality in a Dataset’s Metadata

Extensive data quality descriptions as a vital part of a dataset’s metadata are widely accepted, albeit their provision in a formalized manner is often lacking. This is due to a number of problems that are frequently encountered by geodata producing scientists. As one of these problems, we identiﬁed missing, unknown or unused options to model inhomogeneity of data quality across space, time, and theme in a dataset’s metadata. Detailed information of inhomogeneous geodata quality beyond dataset-wide statistical measures (variance, min, max, etc.) is often only described in dataset accompanying papers or quality reports. These text-based approaches prevent precise querying and hinder the development of advanced data discovery tools that could make valuable use of inhomogeneous data quality information. We propose a proﬁle for the data quality vocabulary (DQV) 1 that allows to model inhomogeneous geodata quality. Considering established vocabularies typically used to describe geographic meta-data, as well as ensuring compatibility with the default version of DQV, enhances the usability and thus, minimizes the effort for data producers to provide formalized descriptions of inhomogeneous data quality.
Understanding Nullstellensatz for QBFs

QBF proof systems are routinely adapted from propositional logic along with adjustments for the new quantifications. Two main successful frameworks currently exist, the reduction [23] and expansion [7] frameworks, inspired by QCDCL [32] and CEGAR solving [22] respectively. However, the reduction framework, while immensely useful in line-based proof systems, is not refutationally complete for static proof systems. Nullstellensatz (NS,[6]) is a well known static propositional proof system, inspired by Hilbert’s theorem [21] of the same name. It falls into the category of algebraic proof systems such as the Polynomial Calculus (PC,[14]) or the Ideal Proof System (IPS,[19]). In this paper, we initiate the study of the NS proof system for QBFs, using the existing expansion ( ∀ Exp) framework and a new “ ∀ Strat” framework. We introduce four new static, QBF refutation systems: ∀ Exp+ NS, ∀ Exp+ NS ′ , ∀ Strat+ NS and ∀ Strat+ NS ′ , which use NS and a more powerful version of NS (NS ′ ) with twin variable encoding that allows it to simulate tree-like Resolution without an exponential blowup. We explore relationships among the proposed systems and analyse their proof sizes for a few well-known hard QBF-families. We find that ∀ Exp+ NS ′ and ∀ Strat+ NS ′ are incomparable. This result is in line with the incomparability result between ∀ Exp+Res and Q-Res [10].
VU Research Portal Experiences in using practitioner's checklists to evaluate the industrial relevance of requirements engineering experiments

Background: A grand challenge for Requirement Engineering (RE) research is to help practitioners understand which RE methods work in what contexts and why. RE researchers recognize that for an RE method to be adopted in industry, RE practitioners should be able to evaluate the relevance of empirical studies to their practice. One possible approach to relevance evaluation is the set of perspective-based checklists proposed by Kitchenham et al. Specifically, the checklist from the practitioner’s perspective seems to be a good candidate for evaluating the relevance of RE studies to RE practice. However, little is known about the applicability of this checklist to the RE field. Moreover, this checklist also requires a deeper analysis of its reliability. Aim: We propose a perspective-based checklist to the RE community that allows evaluating the relevance of experimental studies in RE from the practitioner’s/consultant’s viewpoint. Method: We followed an iterative design-science based approach in which we first analyzed the problems with a previously published checklist and then developed an operationalized proposal for a new checklist to counter these problems. We performed a reliability evaluation of this new checklist by having two practitioners apply the checklist on 24 papers that report experimental results on software requirements specifications’ comprehensibility. Results: We report first-hand experiences of practitioners in evaluating the relevance of primary studies in RE, by using a perspective-based checklist. With respect to the reliability of the adjusted checklist, 9 of out 19 questions show an acceptable proportion of agreement (between two practitioners). Conclusions: Based on our experience, the contextualization and operationalization of a perspective-based checklist helps to make it more useful for the practitioners. However, to increase the reliability of the checklist, more reviewers and more discussion cycles are necessary
, H., Jenkins, M., & Parry, E. (2019). Mapping Espoused Organizational Values. Journal of Business Ethics, 159(1), 133-148.

This paper develops an inventory and conceptual map of espoused organizational values. We suggest that espoused values are fundamentally different to other value forms as they are collective value statements that need to coexist as a basis for organizational activity and performance. The inventory is built from an analysis of 3112 value items espoused by 554 organizations in the UK and USA in both profit and not-for-profit sectors. We distil these value items into 85 espoused value labels, and these are assessed in terms of their similarity and difference through judgements made by 53 experienced individuals. The resulting conceptual map facilitates the evaluation of values which are espoused at the organizational level, as opposed to aggregations of personal values, an important distinction that is often ignored in the literature. This analysis identifies a number of distinct areas of emphasis occupied by espoused values. In particular, the richness of value labels that relates to broader ethical issues may be aimed at external stakeholder management, but also may have an increasing influence on organizational behaviour as they are embedded into organizational practices. By advancing our understanding of espoused values, through an analysis of those being used in practice, we provide a means by which future research into organizational values and ethical issues can progress.
