Objectives and Challenges in Finnish Software Companies 2018 - Interview of 99 Finnish Software Development Firms
2019
The business domain of software development growth increasingly during 2018 and while software companies in Finland are taking benefit of this momentum, they are facing multiple internal and external challenges. We constructed annual software business survey for 99 enterprise to micro-size software companies in Finland. Based on our survey, software development firms aim at growing rather than improving efficiency or changing focus. The focus remains on strengthening the current business instead of aligning it with the market transition, although the lack of competence and resources is remarkable. This poster paper gives a prompt overview of the Finnish software business domain and how soft…
Self-organization of repetitive spike patterns in developing neuronal networks in vitro
2010
The appearance of spontaneous correlated activity is a fundamental feature of developing neuronal networks in vivo and in vitro. To elucidate whether the ontogeny of correlated activity is paralleled by the appearance of specific spike patterns we used a template-matching algorithm to detect repetitive spike patterns in multi-electrode array recordings from cultures of dissociated mouse neocortical neurons between 6 and 15 days in vitro (div). These experiments demonstrated that the number of spiking neurons increased significantly between 6 and 15 div, while a significantly synchronized network activity appeared at 9 div and became the main discharge pattern in the subsequent div. Repetiti…
Temporally precise control of single-neuron spiking by juxtacellular nanostimulation
2017
Temporal patterns of action potentials influence a variety of activity-dependent intra- and intercellular processes and play an important role in theories of neural coding. Elucidating the mechanisms underlying these phenomena requires imposing spike trains with precisely defined patterns, but this has been challenging due to the limitations of existing stimulation techniques. Here we present a new nanostimulation method providing control over the action potential output of individual cortical neurons. Spikes are elicited through the juxtacellular application of short-duration fluctuating currents (“kurzpulses”), allowing for the sub-millisecond precise and reproducible induction of arbitr…
Information System Development Methodologies
2000
This paper provides preliminary results of INDEHELA-M, a joint Finnish-Nigerian project undertaken by a prominent Nigerian software development company. The main objectives of the project are to produce empirical information and understanding of the practice and problems of information systems development (ISD) in Nigeria, and to facilitate Nigerian ISD practitioners by improved methods, techniques, practices, and education, according to their needs. Gender participation in ISD was also introduced to study the methodologies employed in ISD projects and the effect (if any) on gender participation and/or access to information technology and create gender balance awareness in Software Developm…
A STEEPLED Analysis of the SPI Manifesto
2019
Software Process Improvement (SPI) has been founded on the belief that a well-defined and executed process is likely to produce a high-quality pro-duct. Improving a product might provide insights for future improvement efforts. However, this bottom-up approach does not necessarily lead to improvement, considering in particular that software products/artefacts are usually, unique. In contrast, an improved process is a top-down approach, which is applicable to all products (outputs and outcomes). The SPI Manifesto places people, business focus, and organisational change at the core of Software Process Improvement practices. In so doing, certain SPI principles guide the behaviour of individual…
Assessing the Impact of Temporary Retail Price Discounts Intervals Using SVM Semiparametric Regression
2009
Although the marketing literature has found that temporary retail price discounts cause a significant sales increase, little is known about the specific characteristics of deals that influence the magnitude of the sales spike. In this paper, we analyse the impact of the length of temporary retail price discounts periods on the sales increase using scanner-store daily-sales data for two frequently purchased product categories: ground coffee (a storable category) and yogurt (a perishable category).Wedevelop a robust semiparametric regression model based on support vector statistical theory with several previously proposed predictors along with a daily time description. This model also makes i…
Regularity of Spike Trains and Harmony Perception in a Model of the Auditory System
2011
Spike train regularity of the noisy neural auditory system model under the influence of two sinusoidal signals with different frequencies is investigated. For the increasing ratio m/n of the input signal frequencies (m, n are natural numbers) the linear growth of the regularity is found at the fixed difference (m - n). It is shown that the spike train regularity in the model is high for harmonious chords of input tones and low for dissonant ones.
Key Influencing Factors in Early-Stage Hardware Startups: A Trilateral Model of Speed, Resource, and Quality
2020
Hardware startups, i.e., wearable devices, robotics, and Internet of Things, are a significant sector of technology startups, in which software development is relevant and needed. Compared to pure software startups, hardware development in startup contexts lacks a systematic approach and guidelines. This chapter describes an empirical model that captures common elements in product development approaches among many hardware startups. Grounded from insights of 18 active hardware startups, we constructed a trilateral model of resource, speed, and quality in early-stage product development. For startups with relevant contexts, the work suggests the preparation of internal, external resources, a…
Teacher response pursuits in whole class post-task discussions
2020
This paper explores teacher elicitation practices following a perceived absence of a response to an initial inquiry. Specifically, we focus on whole class post-task discussions where a teacher pursues responses in post-first position following students’ non-uptake, and thus makes her orientation toward the expectation of a response publicly available. The data for this study come from 30 h of video-recorded classroom interactions in an English as a medium of instruction university in Turkey. Using Conversation Analysis, this study demonstrates that when confronted with a non-response to her initial elicitation in whole class interaction, in addition to drawing on interactional resources (e.…
Reengineering an Approach to Model-Driven Development of Business Apps
2015
Despite a perceived convergence in mobile application development, platforms such as Android and iOS remain largely incompatible. Supporting multiple platforms currently requires either separate native development (for each system) or utilization of a cross-platform development framework. While many such frameworks have been developed, only few are mature and even less are used widely, let alone commercially. Moreover, they typically are limited with regard to performance and to preserving a native look & feel. Worst of all, their usefulness for business apps is limited due to their low level of abstraction. In this paper, we take a closer look at an academic prototype that employs model-dr…
