A paper waste prediction model
The aim of this paper is to develop a model predicting the collected amount of
waste paper at the regional level of municipalities. Leaming about the factors
that influence the amount of collected paper is a prerequisite for the evaluation
and reorganization of collection systems. We hypothesize that the amount of
collected paper depends on both, the waste potential and factors which influence
the convenience such as the density of collection sites.
For this study, we use a sample of 649 municipalities. The data show a high
variance in terms of the collected waste paper per person and year between the
municipalities. We develop a multivariate regression model providing valuable
insights about the relationship between demographic parameters and the amount
of collected waste paper. Furthermore, in this novel approach we found a
significant positive impact of the convenience of the collection system
Brand personality and its influence on brand loyalty - Do sophisticated brands have more brand loyal customers?
Objectives. Creating loyal customers is one of the most important aims organisations have. However, most marketing departments try to create loyal customers through customer loyalty programmes only. This study aims at investigating the influence of the brand’s image (i.e., brand personality; Aaker, 1997) on brand loyalty.
Method. Study 1 (N = 360) was used to derive a valid single-item measure from a multi-item scale for the three inter-culturally stable brand personality dimensions (sincerity, excitement, sophistication; Aaker, Benet-Martinez, & Garolera, 2001). Study 2, using an automobile customer sample (N = 1032), assessed the influence of brand personality on brand loyalty while controlling for previous purchases and customer personality.
Results. Previous purchases and customers’ conscientiousness were significant determinants of brand loyalty. Additionally, all three brand personality dimensions explained incremental variance (ΔR² = .28) of customers’ loyalty.
Conclusion. Practical implications for the application of brand personality in loyalty campaigns are derived
Buy Three to Waste One? How Real-World Purchase Data Predict Groups of Food Wasters
Approximately one-third of all food produced for human consumption is either lost or wasted. Given the central position of retailers in the supply chain, they have the potential to effectively reduce consumer food waste by implementing targeted interventions. To do so, however, they should target distinct consumer groups. In this research, we use a unique data set comprising the grocery shopping data of customers who use loyalty cards, complemented with food waste reports, to derive three distinct target groups: traditionals, time-constrained, and convenience lovers. Based on the general behavioral change literature, we discuss diverse target group-specific interventions that retailers can implement to reduce consumer food waste. Overall, we pave a research path to examine how retailers and marketing can effectively shift consumer behavior toward more sustainable food and shopping practices and assume responsibility within the food supply chain
Remittance flows to post-conflict states: perspectives on human security and development
This repository item contains a single issue of the Pardee Center Task Force Reports, a publication series that began publishing in 2009 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future.Migrant remittances – that is, money or other goods sent to relatives in the country of origin– play an increasingly central role in post-conflict reconstruction and national development of conflict-affected states. Private remittances are of central importance for restoring stability and enhancing human security in post-conflict countries. Yet the dynamics of conflict-induced remittance flows and the possibilities of leveraging remittances for post-conflict development have been sparsely researched to date.
This Pardee Center Task Force Report is the outcome of an interdisciplinary research project organized by the Boston University Center for Finance, Law & Policy, in collaboration with The Frederick S. Pardee Center for the Study of the Longer-Range Future. The Task Force was convened by Boston University development economist John R. Harris and international banking expert Donald F. Terry, and social anthropologist Daivi Rodima-Taylor, Visiting Researcher at the Boston University African Studies Center, served as lead researcher and editor for the report. The Task Force was asked to research, analyze, and propose policy recommendations regarding the role of remittances in post-conflict environments and their potential to serve as a major source of development funds. The report’s authors collectively suggest a broader approach to remittance institutions that provides flexibility to adapt to specific local practices and to make broader institutional connections in an era of growing population displacement and expanding human and capital flows. Conditions for more productive use of migrants’ remittances are analyzed while drawing upon case studies from post-conflict countries in Africa, Asia and Latin America.
The papers in this Task Force Report establish the importance of remittances for sustaining local livelihoods as well as rehabilitating institutional infrastructures and improving financial inclusion in post-conflict environments. Highlighting the increasing complexity of global remittance systems, the report examines the growing informality of conflict-induced remittance flows and explores solutions for more efficient linkages between financial institutions of different scales and degrees of formality. It discusses challenges to regulating international remittance transfers in the context of growing concerns about transparency, and documents the increasing role of diaspora networks and migrant associations in post-conflict co-development initiatives. The Task Force Report authors outline the main challenges to leveraging remittances for post-conflict development and make recommendations for further research and policy applications
A Cross-National Investigation into the Marketing Department\u27s Influence Within the Firm: Toward Initial Empirical Generalizations
This study of the influence of the marketing department (MD), as well as its relationship with firm performance, includes seven industrialized countries and aims to generalize the conceptual model presented by Verhoef and Leeflang (2009). This investigation considers the antecedents of perceived MD influence, top management respect for the MD, and MD decision influence, as well as the relationships of these three influence variables with market orientation (MO) and business performance (BP). Meta-analytic procedures reveal initial empirical generalizations: Accountability, MD innovativeness, and the customer connection capabilities of the MD relate consistently to all three studied MD influence measures. The generalization also shows that MD influence contributes to BP indirectly through its positive relationship with MO and directly through its positive direct relationship with BP
IgE Mediated Autoallergy against Thyroid Peroxidase – A Novel Pathomechanism of Chronic Spontaneous Urticaria?
Chronic spontaneous urticaria (csU), which is characterized by recurrent episodes
of mast cell-driven wheal and flare-type skin reactions, is often associated with
elevated total IgE levels and thyroid autoimmunity. We speculate that some csU
patients express IgE autoantibodies against thyroid antigens such as thyroid
peroxidase (TPO), which could bind to skin mast cells and induce their
activation.We developed and used a site-directed human IgE capture ELISA to quantify
IgE-anti-TPO. We used this assay and investigated csU patients
(n = 478) and healthy control subjects
(n = 127) for IgE-anti-TPO and then assessed
IgE-anti-TPO-positive and -negative csU patients for clinical and serological
differences. ( = 61%, IgE-anti-TPO:
median 6.67, interquartile range 5.39–8.24). IgE-anti-TPO-positive and
-negative csU patients had very similar distributions of age and gender as well as
disease activity and duration. IgE-anti-TPO-positive csU patients exhibited
significantly higher IgG-anti-TPO levels and lymphocyte counts as well as
decreased C4 complement levels.Our findings show that a sizeable subgroup of csU patients expresses IgE
antibodies against thyroid peroxidase. These autoantibodies could cause
“autoallergic” mast cell activation, a novel pathomechanism of chronic
spontaneous urticaria
Metabolism and Regulation of Glycerolipids in the Yeast Saccharomyces cerevisiae
Due to its genetic tractability and increasing wealth of accessible data, the yeast Saccharomyces cerevisiae is a model system of choice for the study of the genetics, biochemistry, and cell biology of eukaryotic lipid metabolism. Glycerolipids (e.g., phospholipids and triacylglycerol) and their precursors are synthesized and metabolized by enzymes associated with the cytosol and membranous organelles, including endoplasmic reticulum, mitochondria, and lipid droplets. Genetic and biochemical analyses have revealed that glycerolipids play important roles in cell signaling, membrane trafficking, and anchoring of membrane proteins in addition to membrane structure. The expression of glycerolipid enzymes is controlled by a variety of conditions including growth stage and nutrient availability. Much of this regulation occurs at the transcriptional level and involves the Ino2–Ino4 activation complex and the Opi1 repressor, which interacts with Ino2 to attenuate transcriptional activation of UASINO-containing glycerolipid biosynthetic genes. Cellular levels of phosphatidic acid, precursor to all membrane phospholipids and the storage lipid triacylglycerol, regulates transcription of UASINO-containing genes by tethering Opi1 to the nuclear/endoplasmic reticulum membrane and controlling its translocation into the nucleus, a mechanism largely controlled by inositol availability. The transcriptional activator Zap1 controls the expression of some phospholipid synthesis genes in response to zinc availability. Regulatory mechanisms also include control of catalytic activity of glycerolipid enzymes by water-soluble precursors, products and lipids, and covalent modification of phosphorylation, while in vivo function of some enzymes is governed by their subcellular location. Genome-wide genetic analysis indicates coordinate regulation between glycerolipid metabolism and a broad spectrum of metabolic pathways
The Migration State in the Global South: Nationalizing, Developmental and Neoliberal Models of Migration Management
How do states in the Global South manage cross-border migration? This article identifies Hollifield’s “migration state” as a useful tool for comparative analysis yet notes that in its current version the concept is limited, given its focus on economic immigration in advanced liberal democracies. We suggest a framework for extending the “migration state” concept by introducing a typology of nationalizing, developmental, and neoliberal migration management regimes. The article explains each type and provides illustrative examples drawn from a range of case studies. To conclude, it discusses the implications of this analysis for comparative migration research, including the additional light it sheds on the migration management policies of states in the Global North
The effects of custodial vs. non-custodial sentences on re-offending: A systematic review of the state of knowledge
As part of a broad initiative of systematic reviews of experimental or quasiexperimental
evaluations of interventions in the field of crime prevention and the
treatment of offenders, our work consisted in searching through all available databases
for evidence concerning the effects of custodial and non-custodial sanctions on reoffending.
For this purpose, we examined more than 3,000 abstracts, and finally 23
studies that met the minimal conditions of the Campbell Review, with only 5 studies
based on a controlled or a natural experimental design. These studies allowed, all in all,
27 comparisons. Relatively few studies compare recidivism rates for offenders
sentenced to jail or prison with those of offenders given some alternative to
incarceration (typically probation).
According to the findings, the rate of re-offending after a non-custodial sanction is
lower than after a custodial sanction in 11 out of 13 significant comparisons. However,
in 14 out of 27 comparisons, no significant difference on re-offending between both
sanctions is noted. Two out of 27 comparisons are in favour of custodial sanctions.
Finally, experimental evaluations and natural experiments yield results that are less
favourable to non-custodial sanctions, than are quasi-experimental studies using softer
designs. This is confirmed by the meta-analysis including four controlled and one
natural experiment. According to the results, non-custodial sanctions are not beneficial
in terms of lower rates of re-offending beyond random effects. Contradictory results
reported in the literature are likely due to insufficient control of pre-intervention
differences between prisoners and those serving “alternative” sanctions
