Reviewing the field of external knowledge search for innovation: theoretical underpinnings and future (re-)search directions – a review of how firms search for innovation outside. They introduce the term decoupled search which happens when the search process involves an assistant.

Charting a Path between Firm‐Specific Incentives and Human Capital‐Based Competitive Advantage – firms can offer unique incentives to their employees (e.g. Disney parks’ discount to employees, Google enabling employees access to interesting data, having a culture of fun at Zappos ). The paper provides a typology of these different incentives that can be unique to certain firms.

Scale quickly or fail fast: An inductive study of acceleration – accelerators have three main characteristics: investment on ventures that already reached product-market fit, focus on growth (through revenue, number of customers and even team maturity) in a short amount of time and an emphasis on aggressively testing whether the venture can succeed or fail.

Detecting academic fraud using Benford law: The case of Professor James Hunton – Benford’s law states that the first digit of datasets collected would likely to be small. For instance, the number 1 appears 30% of the time if a dataset if collected truthfully. The researchers used this idea to see whether they can detect the fraud from retracted papers.

A Quantum Approach to Paradox Entails Neither Preexisting Tensions Nor Asymmetry: Response to Li – So, this was a letter in response to a comment by Li on the original article by Hahn and Knight using concepts from quantum physics to resolve the paradoxes in management research. I wouldn’t claim that I understand anything but it’s really fascinating the extent that researchers are adapting theories from other fields.

The Role of Research in Business Schools and the Synergy Between its Four Subdomains – applies Pasteur’s quadrants to create a typology of business research. I liked the part described how famous names in management fit into the different quadrants.

Crossing the valley of death: Five underlying innovation processes – They describe five processes to cross the so-called valley of death, hindering early-stage ventures from succeeding. These include: refining the narrative for the technology concept, evaluating the technical aspects of the lab-scale models, refining how the technology will be used, assessing the comparative value and integrating the inputs of innovator actors.

ON THE THEORY OF ORGANIZATIONAL PATH DEPENDENCE: CLARIFICATIONS, REPLIES TO OBJECTIONS, AND EXTENSIONS – a follow up to the highly cited article in 2009 on organizational path dependence

The Transformation of the Innovation Process: How Digital Tools are Changing Work, Collaboration, and Organizations in New Product Development – digital tools “not only do they affect output and process efficiency, but they also increase depth and breadth of the work of individual innovators, they lead to rearrangement of the entire innovation processes, enable new configurations of people, teams, and firms”

Why ‘Doing Well By Doing Good’ Goes Wrong: A Critical Review of ‘Good Ethics Pays’ Claims in Managerial Thinking – it has been quite an accepted idea these days that companies should do good as its good for their bottom line. I remember listening to a podcast episode from Econtalk a few weeks ago that touches this (which I highly recommend). Nonetheless, this AOM review is fascinating as it forces us to revisit our assumptions.

The creative cliff illusion – people assume that their creativity will drop over time. This study however demonstrates that this is not the case and that having such negative assumptions can be detrimental to performance.

The role of immigration in innovation has gotten a lot of attention this week (ex. from In the Pipeline, Brookings). The piece that resonated a lot to me is this editorial introducing the special issue of Research Policy on immigration.

The authors introduced their article with 4 quotes, which then anchored the different perspectives to explore immigration.

Self-selection among immigrants and role in the diffusion of innovation

“Migration has one characteristic that should make it very effective as a diffusion method. The hardships occasioned with [it] will usually discourage all but the most resourceful, energetic, and courageous. Those who have the hardihood to venture in this way hence are likely to have exactly those human qualities which are most essential to innovating and diffusing”

-Warren C. Scoville (“Spread of Techniques: Minority Migrations and the Diffusion of Technology”, Journal of Economic History 1951: 11/4, p.349)

Arguments against brain-drain and for the value of choice

“… even were it possible to force the professionals to stay at home, it would be a foolish policy. Lack of congenial working conditions, absence of peer professionals to interact with, and resentment at being deprived of the chance to emigrate can lead to a wholly unproductive situation in which one has the body but not the brain. The brain is not a static thing: it can drain away faster sitting in the wrong place than when travelling to Cambridge or Paris!”

Jagdish Bhagwati (In Defense of Globalisation, Oxford University Press: 2007; p.214)

Struggles in assimilating and in being away

“Le véritable lieu de naissance est celui où l’on a porté pour la première fois un coup d’oeil intelligent sur soi-même: mes premières patries ont été des livres, à un moindre degré, des écoles.”
(The real birthplace is where you first took an intelligent look at yourself: my first countries were books, to a lesser extent, schools.)

Marguerite Yourcenar (Mémoires d’Hadrien, Plon: 1951)

Job market

“We hire from the best schools. All the people who go to those schools […] we offer jobs to American, non-American, that’s who we build these product teams around. And so, because we’re in a very competitive business, we don’t compromise on that. Wherever we can get those people, that’s where we create the jobs.”

Bill Gates (National Public Radio interview, March 12, 2008; https://www.npr.org/transcripts/88154016– last visit May 2020)

I needed to familiarize myself with the literature on science entrepreneurship (for reasons I’m going to explain soon). After delving into bibliometrics and doing literature review repetitively for my PhD, I already have a system to efficiently introduce myself to a new literature. In this post, I will explain my process, hoping it helps others who are also entering a new field.

I typically follow these steps:

1. Explore the Web of Knowledge using a keyword search
2. Explore data in Python
3. Create visualizations using VosViewer

The first step for me is usually just trying out different keywords in the Web of Knowledge. I then browse the first page of the latest articles and the top cited articles. I try to check whether these are related to my topic of interest.

For this topic of science entrepreneurship, I settled with the following keywords. I also narrowed it down to the management journals that I know are relevant to technology and innovation management and just general management. Moreover, I was just interested in the papers published from 2010. Below was my keyword search:

TS=(science OR technology ) AND TS=(startup* OR “start up” OR “new venture” OR entrepreneur* OR “new firm” OR “spin off” OR spinoff* OR SME OR SMEs) AND SO=(RESEARCH POLICY OR R D MANAGEMENT OR STRATEGIC MANAGEMENT JOURNAL OR JOURNAL OF PRODUCT INNOVATION MANAGEMENT OR ACADEMY OF MANAGEMENT REVIEW OR ACADEMY OF MANAGEMENT JOURNAL OR TECHNOVATION OR SCIENTOMETRICS OR TECHNOLOGICAL FORECASTING “AND” SOCIAL CHANGE OR TECHNOLOGY ANALYSIS STRATEGIC MANAGEMENT OR ORGANIZATION SCIENCE OR ADMINISTRATIVE SCIENCE QUARTERLY OR JOURNAL OF BUSINESS VENTURING OR INDUSTRY “AND” INNOVATION OR STRATEGIC ENTREPRENEURSHIP JOURNAL OR JOURNAL OF TECHNOLOGY TRANSFER OR JOURNAL OF ENGINEERING “AND” TECHNOLOGY MANAGEMENT OR JOURNAL OF MANAGEMENT OR JOURNAL OF MANAGEMENT STUDIES OR RESEARCH TECHNOLOGY MANAGEMENT OR ENTREPRENEURSHIP THEORY “AND” PRACTICE OR ACADEMY OF MANAGEMENT ANNALS OR ACADEMY OF MANAGEMENT PERSPECTIVES OR JOURNAL OF BUSINESS RESEARCH OR BRITISH JOURNAL OF MANAGEMENT OR EUROPEAN JOURNAL OF MANAGEMENT OR MANAGEMENT SCIENCE)

After exploring the results, I then downloaded the articles. These amounted to 1412 articles in total. Since WOS only allowed downloading of 500 at a time, I named these files 1-500.txt, 501-1000.txt and so on. I saved all the files in a folder (named Raw in this case) in my computer.

Data Exploration in Python

In the following, I show the code to import the data into Python and format the articles into a pandas dataframe.

import re, csv, os 
import pandas as pd
import numpy as np
import nltk
import math
%matplotlib inline
import seaborn as sns
import matplotlib.pyplot as plt
sns.set_style('white')
from collections import Counter

columnnames =['PT','AU','DE', 'AF','TI','SO','LA','DT','ID','AB','C1','RP','EM','CR','NR','TC','U1','PU','PI','PA','SN','EI','J9','JI','PD','PY','VL','IS','BP','EP','DI','PG','WC','SC','GA','UT']

def convertWOScsv(filename):
    openfile = open(filename, encoding='latin-1')
    sampledata = openfile.read()
    # divide into list of records 
    individualrecords = sampledata.split('\n\n')
    databaseofWOS = []
    for recordindividual in individualrecords:
        onefile = {}
        for x in columnnames:
            everyrow = re.compile('\n'+x + ' ' + '((.*?))\n[A-Z][A-Z1]', re.DOTALL)
            rowsdivision = everyrow.search(recordindividual)
            if rowsdivision:
                onefile[x] = rowsdivision.group(1)
        databaseofWOS.append(onefile)
    return databaseofWOS

def massconvertWOS(folder):
    publicationslist = []
    for file in os.listdir(folder):
        if file.endswith('.txt'):
            converttotable = convertWOScsv(folder + '\\' + file)
            publicationslist += converttotable
    publicationslist = pd.DataFrame(publicationslist)
    publicationslist.dropna(how='all', inplace=True)
    publicationslist.reset_index(drop=True, inplace=True)
    publicationslist['PY'] =publicationslist['PY'].fillna('').replace('', '2019').astype(int)
    publicationslist['TC'] = publicationslist['TC'].apply(lambda x: int(x.split('\n')[0]))
    return publicationslist

df = massconvertWOS('Raw')
df = df.drop_duplicates('UT').reset_index(drop=True)

I preview some of the articles that I was able to download below. I chose the relevant columns to show.

print('Number of Articles:', df.shape[0])
df.head()[['TI', 'AU', 'SO', 'PY']]

WOS is smart in the sense that even if the text does not contain the keywords you said, they still may include papers because they sense that these are relevant papers. To filter out these papers that did not contain the keywords I wanted, I further filtered the dataset by checking the title, abstract and author-selected keywords. Moreover, let’s remove articles without any citations.

df["txt"] = df["TI"].fillna("") + " " + df["DE"].fillna("") + " " + df["AB"].fillna("")
df["txt"] = df["txt"].apply(lambda x: x.replace('-', ' '))
df = df[df['txt'].apply(lambda x: any([y in x.lower() for y in ['scien', 'technolog']]))]
df = df[df['txt'].apply(lambda x: any([y in x.lower() for y in ['startup', 'start up', 'new venture', 'entrepreneur', 'new firm', 'spin off',
                                                                'spinoff', 'sme ', 'smes ']]))]
df = df[~df['CR'].isnull()] 
print('Number of Articles:', df.shape[0])

Number of Articles: 846

I can plot the number of articles over time

df.groupby('PY').size().plot(kind='bar')

I can look at the breakdown per journal

#df.groupby('SO').size().sort_values().plot(kind='barh', figsize=[5,10])
soplot = df.pivot_table(index='PY', columns='SO', aggfunc='size').fillna(0) #.reset_index()
soplot = soplot[soplot.sum(axis=0).sort_values().index].reset_index().rename(columns={'PY':'Year'})
soplot['Year'] = pd.cut(soplot['Year'], [0, 2014, 2019], labels=['2010-2014', '2015-2019'])
soplot.groupby('Year').sum().T.plot(kind='barh', stacked=True, figsize=[5,10])
plt.ylabel('Journal'), plt.xlabel('Number of Articles')
plt.show()

I can look at the top cited articles. This shows what are the foundational material that I should know before delving into the topic.

topcited = df['CR'].fillna('').apply(lambda x: [y.strip() for y in x.split('\n')]).sum()
pd.value_counts(topcited).head(10)

The articles above are not really very specific to our topic of interest. These are foundational papers in innovation/management. To explore those papers that are more relevant to our topic, what I can do then is find which is the most cited within the papers in this dataset, meaning hey include the keywords that I’m interested in. This is the internal citation of the papers.

def createinttc(df):
    df["CRparsed"] = df["CR"].fillna('').str.lower().astype(str)
    df["DI"] = df["DI"].fillna('').str.lower()
    df["intTC"] = df["DI"].apply(lambda x: sum([x in y for y in df["CRparsed"]]) if x!="" else 0)
    df["CRparsed"] = df["CR"].astype(str).apply(lambda x: [y.strip().lower() for y in x.split('\n')])
    return df

df = createinttc(df).reset_index(drop=True)

df.sort_values('intTC', ascending=False)[['TI', 'AU', 'SO', 'PY', 'intTC']].head(10)

A complementary approach is to look at the articles that are citing the most the rest of the papers in the dataset. These allows us to see which reviews already integrates the studies within our dataset. We can then start reading from this set of papers as they cover already a lot of the other papers in the dataset.

doilist = [y for y in df['DI'].dropna().tolist() if y!='']
df['Citing'] = df['CR'].apply(lambda x: len([y for y in doilist if y in x]))

Bibliometric Analysis in VosViewer

To create visualizations of the paper, we do the following steps. First, we can export the filtered dataset into a text file.

def convertWOStext(dataframe, outputtext):
    dataframe["PY"]=dataframe["PY"].astype(int)
    txtresult = ""
    for y in range(0, len(dataframe)):
        for x in columnnames:
            if dataframe[x].iloc[y] != np.nan:
                txtresult += x + " " + str(dataframe[x].iloc[y]) + "\n"
        txtresult += "ER\n\n"
    f = open(outputtext, "w", encoding='utf-8')
    f.write(txtresult)
    f.close()

convertWOStext(df, 'df.txt')

We can then open the file in VosViewer. From there, we can create various visualizations. I like using bibliographic coupling to map all the papers in the dataset

I saved the file in VosViewer. This gives you two files, one has the data on each document and the second file has the network data. We modify these files to make certain changes. First, the citations above reflect their citations from all the papers outside the dataset. I want the internal citations to be shown so I replace it.

def createvosfile1(filename, df, updatecit= False, newclusters = False, newname=None):
    vosfile1  = pd.read_csv(filename, sep="\t")
    voscolumns = vosfile1.columns
    vosfile1["title"] = vosfile1["description"].apply(lambda x: x.split("Title:</td><td>")[1])
    vosfile1["title"] = vosfile1["title"].apply(lambda x: x.split("</td></tr>")[0])
    df["TI2"] = df["TI"].apply(lambda x: " ".join(x.lower().split()))
    vosfile1 = vosfile1.merge(df[[x for x in df.columns if x not in voscolumns]], how="left", left_on="title", right_on="TI2")
    vosfile1["txt"] = vosfile1["TI"].fillna(" ") + " " + vosfile1["DE"].fillna(" ") + " " + vosfile1["AB"].fillna(" ")  
    vosfile1["txt"] = vosfile1["txt"].apply(lambda x: x.lower())
    vosfile1["weight<Citations>"] = vosfile1["intTC"].fillna(0)
    vosfile1 = vosfile1.drop_duplicates('id')
    vosfile1['id'] = vosfile1.reset_index().index + 1
    if newclusters == True:
        vosfile1['cluster'] = artclusters
    if updatecit == True:
        vosfile1[voscolumns].to_csv(newname, sep="\t", index=False)
    return vosfile1

df = createvosfile1('Processed\VosViewer_1_Original.txt', df, newname='Processed\VosViewer_1_intCit.txt', updatecit= True, newclusters=False)

The above network just uses the citation data of the publications. To improve it, I like integrating the textual data from the title, abstract and keywords. I followed the steps suggested here for cleaning the text (https://www.analyticsvidhya.com/blog/2016/08/beginners-guide-to-topic-modeling-in-python/). I then combine these two measures to allow for hybrid clustering

Liu, Xinhai, Shi Yu, Frizo Janssens, Wolfgang Glänzel, Yves Moreau, and Bart De Moor. “Weighted hybrid clustering by combining text mining and bibliometrics on a large‐scale journal database.” Journal of the American Society for Information Science and Technology 61, no. 6 (2010): 1105-1119.

dfhybrid = createhybridnet(df, 0.5)
createvosviewer2filefromhybrid(dfhybrid, 0, r'Processed/VosViewer_2_Hybrid.txt')

If we reimport these modified files to VosViewer. We come up with this visualization which incorporates both textual and citation data.

I can then spend tons of time just exploring the network. I look at the papers in each cluster. I check which papers have high citations. I can do this also with the help of python. We can update the clustering using the one generated by VosViewer.

Discoverers in scientific citation data – this research finds that there are a group of researchers who are good at discovering (or citing early) potentially important papers. This reminds me of the book Superforecasting which talks about how some people are better than others in forecasting the future.

Choices and Consequences: Impact of Mobility on Research-Career Capital and Promotion in Business Schools – In a study of 376 professors in European business schools, they find that mobility is useful in building research careers. At the same time, moving too much can also delay promotions.

The Art of the Pivot: How New Ventures Manage Identification Relationships with Stakeholders as They Change Direction – there is so much emphasis these days for startups to be able to pivot. The problem however is that pivoting is not so easy when you have many stakeholders to appease. This research gives insights on how to manage such relationships with important stakeholders when a startup needs to pivot.

Political skills and career success of R&D personnel: a comparative mediation analysis between perceived supervisor support and perceived organisational support – like many things, the technical superiority of an entity (whether it’s a product, firm or an employee) does not guarantee its success. In this study, they look at R&D employees and find that political skills are important for one to get ahead in one’s career.

Collaborative patents and the mobility of knowledge workers – In my field of FBDD, research mobility seems to be one of the most important mechanisms for the knowledge to spread. In this study of the European biotech sector, inventors who were previously located together are found to form collaborations faster.

Taking leaps of faith: Evaluation criteria and resource commitments for early-stage inventions – Researchers use text mining to quantify how technology transfer office evaluate and decide to financially back a new invention. They find that feasibility and desirability (expressed through words used in the examination document) are important for new inventions.

Exploration versus exploitation in technology firms: The role of compensation structure for R&D workforce – people respond to incentives. This study explores how a firm can structure its incentives as a lever to incentivize exploration / exploitation. In this study, the researchers find that firms with ” higher-powered tournament incentives in vertical compensation structure report higher fraction of innovation directed towards exploration”

Aligning technology and institutional readiness: the adoption of
innovation – It’s always exciting to explore how big firms adopt innovation. While technological readiness is important, researchers in this paper introduce that it should be complemented with the idea of institutional readiness.

Team efficiency and network structure: The case of professional League of Legends – with the amount of data generated by Esports, we should expect more management insights coming from them. In this study, they look at the effect of team interactions/centrality on team performance.

For the next month, I’ll be at the University of Cambridge to conduct a study on how fragment-based drug discovery thrived in the area.

The Legitimacy Threshold Revisited: How Prior Successes and Failures Spill Over to Other Endeavors on Kickstarter – previous outcomes in Kickstarter affect future crowdfunding efforts by “encouraging audiences to repeatedly support other related endeavors or by discouraging them from doing so.”

The Time Efficiency Gain in Sharing and Reuse of Research Data – sharing research data can yield to efficiency gains to the scientific community

Does combining different types of collaboration always benefit firms? Collaboration, complementarity and product innovation in Norway – conventional thinking dictates that firms should collaborate as much as they can to increase the chances of innovation occurring. This study however finds that pursuing all types of collaborations (in this case, scientific and supply chain) might not be useful all the time as these might interact and may negatively impact innovation.

It’s in the Mix: How Firms Configure Resource Mobilization for New Product Success – networks are always fascinating. Here, they look at the new product development through a network perspective.

Improving the peer review process: a proposed market system – Currently, reviewers do not receive any compensation given the amount of work they have to do. This is bad for science as well because papers do not get reviewed properly/fast enough. Creating a market system for the review process for better incentivization of both authors and reviewers might improve the process.

Federal funding of doctoral recipients: What can be learned from linked data – New datasets are always exciting. Researchers in this study propose linking a huge dataset on university payrolls with another huge survey about PhD graduates. It would be interesting to see how other researchers will use data to understand innovation, basic research, career development to name a few.

Universities and open innovation: the determinants of network centrality – Universities that are located centrally in their university-industry networks are also in better position to generate spinoffs and conduct projects with external funding.

The fragmentation of biopharmaceutical innovation – The pharma industry is not consolidating as much as expected, with smaller firms playing big roles. Commentary by the blog in the pipeline here.

This week seems to be a special one for the field of entrepreneurship, with some publications on the merits of studying it from an academic perspective such as this one A wakeup call for the field of entrepreneurship and its evaluators

Has the Concept of Opportunities Been Fruitful in the Field of Entrepreneurship? – In line with the previous one, this reflects on the concept of opportunities which has always been in the same conversation with entrepreneurship. I have not been able to access the article despite various searchers but I’m sure that it touches on the perennial question on whether opportunities are created or discovered. I find this discussion fascinating because by itself, entrepreneurship research is already too scholarly. Going one step backwards and reflecting on such philosophical questions, perhaps pushes this even further.

Firm Strategic Behavior and the Measurement of Knowledge Flows with Patent Citations –  Ever since I got into bibliometrics, citations have been fascinating. Instead of just a measure of paper’s worth and knowledge flow, citations also reflect other subtle things such as informal ties, cliques and prestige. In this paper, the researchers looked at patent citations and explores how it does not only reflect knowledge flow but also other other factors including firm strategy and intellectual property regime.

Predicting citation counts based on deep neural network learning techniques – in the theme apply neural networks to everything, in this paper, the researchers aimed to predict citation counts of papers. This makes me wonder whether we could reverse the process one day and design an AI that can output papers according to an input citation count.

Optimal Distinctiveness, Strategic Categorization, and Product Market Entry on the Google Play App Platform – optimal distinctiveness is really taking the management literature by storm. It will probably be the next open innovation or absorptive capacity with the growth in publications about it such as this one looking at app success.
