An Information System Design Product Theory for Integrated Order, Transportation and Warehouse Management Systems

2013

Globalization, lead time reduction and cost pressures, and other factors make it nontrivial for most companies to devise and manage effective logistics services to meet client requirements. They are better off using the services of specialized third party logistics service providers. These providers compete fiercely and need to develop and improve their services continuously to gain competitive advantage. Integrating the logistics process for improving communication and coordination is the most feasible way for third party logistics providers to deal with these pressures. Yet, the extant literature provides little theoretical guidance for integrating the logistics life-cycle, including orde…

Identity Use and Misuse of Public Persona on Twitter

2016

Social media sites have appeared during the last 10 years and their use has exploded all over the world. Twitter is a microblogging service that has currently 320 million user profiles and over 100 million daily active users. Many celebrities and leading politicians have a verified profile on Twitter, including Justin Bieber, president Obama, and the Pope. In this paper we investigate the '‘hundreds of Putins and Obamas phenomenon’ on Twitter. We collected two data sets in 2015 containing 582 and 6477 profiles that are related to the G20 leaders’ profiles on Twitter. The number of namesakes varied from 5 to 1000 per leader. We analysed in detail various aspects of the Putin and Erdogan rela…

Cultural Politics of Love and Provision among Poor Youth in Urban Tanzania

2015

This article examines how urban youth in the poorest neighbourhoods of Dar es Salaam negotiate the terms of transactional intimacy, that is, heterosexual relations in which men are expected to provide for women materially. Using the concept of ‘affect’, I argue that this negotiation involves different levels of male providership, as well as moral values attached to notions of ‘true love’ and the Swahili concept of tamaa. Poor men and women view their agency differently within transactional intimacy, with women describing themselves as exploited by men who do not fulfil their end of the transactional bargain, and poor men portraying themselves as deeply disempowered in comparison to wealthie…

Diversity begets diversity: A global perspective on gender equality in scientific society leadership.

2018

Research shows that gender inequality is still a major issue in academic science, yet academic societies may serve as underappreciated and effective avenues for promoting female leadership. That is, society membership is often self-selective, and board positions are elected (with a high turnover compared to institutions)—these characteristics, among others, may thus create an environment conducive to gender equality. We therefore investigate this potential using an information-theoretic approach to quantify gender equality (male:female ratios) in zoology society boards around the world. We compare alternative models to analyze how society characteristics might predict or correlate with the …

Distributed leadership in practice in Finnish schools

2017

ABSTRACTThe aim of this study is to explore what aspects the principals and the members of the management teams in the primary and upper secondary education schools in Vantaa support distributed leadership in their school and how necessary they see that distributed leadership is extended to the students in matters concerning the curriculum and the development of teaching practices. The research method was a survey based on a questionnaire of 48 questions, where the respondents evaluated the preconditions of distributed leadership in their school. The principals and members of the management teams in the primary and upper secondary schools in Vantaa see distributed leadership mostly as deleg…

Creating a collaborative ESL classroom through teacher leadership : a case study in Guizhou Province, China

2016

This research looks into collaborative learning with teacher leadership in the ESL classroom of Guizhou, China. The phenomenon, purpose, research methods, main results and conclusions of the study are provided in the abstract. Under the phenomenon of New High School Curriculum Reform Program in China in 2004, all Chinese schools are trying new teaching methods to improve students’ English level. The purpose of the study is getting a better understanding of collaborative learning with teacher leadership in the ESL classroom. Qualitative research is applied to collect the data from the Chinese school. The research data is collected through two questionnaire surveys (open-ended questionnaires)…

Performance of Lead-Acid Batteries with Nanostructured Electrodes at Different Temperature

2018

In this work we present innovative lead-acid batteries with nanostructured electrodes, which are cycled in a wide range of temperatures typically of lead-acid commercial batteries (EN 61427-1: 2013). In comparison to parameters usually used to commercial batteries, much more stressful conditions in terms of cut-off, charge/discharge rate and discharge were imposed.

High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature

2021

Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…

El edificio gremial de los abaixadors o tundidores, en Valencia

2020

In the ?barri del mercat?, in the city of Valencia and very close to its Lonja, there is a building complex which is the object of this study. The research, carried out from the simple field of toponymy, to the constructive analysis, lead us to suppose that it is the building of the Valencian trade union of cloth-shearers. It can be seen how the building now camouflaged by other subsequent interventions, corresponds to a type that cannot be related to those usually built in the city of Valencia. Its origins clearly from the Valencian self-governing period splendor, its dimensions and the finishes used in its construction seem to refer to a medieval workshop. A structure of great importance …
