Leading Change: Understanding Why Transformation Efforts Often Fail
Authors: Westover Jonathan
Published: August 2024

Abstract: This article discusses common reasons why organizational transformations often fail and provides a framework for more effectively leading change, exploring how resistance to change is natural but must be addressed empathetically rather than dismissively, and how establishing a strong sense of urgency for change is critical yet overlooked as leaders underestimate how important it is to convey that the status quo is unsustainable and major changes are urgently needed, in addition to developing a compelling future vision that frequently lacks vivid imagery and purpose. The article also stresses how transformation efforts commonly neglect organizational politics and key stakeholder interests, and emphasizes the importance of frequent, targeted communication on an ongoing basis to increase buy-in over time, as well as aligning structures and systems to support new goals by removing obstacles like outdated processes and metrics, and truly empowering others at all levels for broad-based action is said to be necessary for sustained progress through unpredictability, using Lego's remarkable turnaround after almost going bankrupt as an example of success through focus on communication, vision, stakeholder buy-in, enablers and empowerment.

Occurrence and life cycle of broomrape (Phelipanche aegyptiaca Pers.) on mustard (Brassica campestris L.) in Northeastern regions of Rajasthan
Authors: Kumari Sarita , Joshi Ridhi , Meena Rishi Kesh , Mishra Preeti
Published: August 2024

Broomrape (Phelipanche and Orobanche) weeds are parasitic on a variety of dicotyledonous plant species, severely harming important cash crops all over the world. The process of broomrape infestation in mustard fields (oilseed crop) is poorly understood in Rajasthan. Over the past few years, the number of broomrape-contaminated mustard fields has increased in many regions of Rajasthan. Field surveys were conducted to investigate the occurrence of broomrape in mustard-growing areas of northeastern Rajasthan. Field studies were also carried out in the extensively broomrape-infested mustard fields in the Nawalgarh region of Jhunjhunu (Rajasthan, India) (27°51'0.00" N 75°16'12.00" E) to evaluate the life stages and severity of broomrape infestation. Phelipanche aegyptiaca Pers. (Egyptian broomrape) was found infesting the fields of Brassica campestris L. Field experiments were conducted to record all the underground and aerial life stages of P. aegyptiaca. Among all the visited plots, the Mukandgarh region exhibited the highest incidence and severity of P. aegyptiaca during the emerging, flowering, and fructification stages, whereas the Nawalri region displayed the lowest incidence and severity at each stage. Mustard yield and quality were severely affected by the Phelipanche infestation. With an average of 50% disease incidence in most of the plots, flowering and fructification stages of broomrape are the most difficult to control and cause 100% infestation to the crop. The interrelationship of P. aegyptiaca and B. campestris is not studied extensively, especially in Rajasthan. To date successful control of this weed is not achieved. The present investigation will help understand the histological interactions of P. aegyptiaca on B. campestris about days of sowing (DAS). These interactions will certainly help to design cultural and biological control strategies by determining the most effective timing of control concerning the timeline of germination and infestation of P. aegyptiaca.

Authors: Nurdiani Dini , Putro Eko Wahyu , Septisetyani Endah Puji , Utami Nuruliawaty , Hariyatun Hariyatun , Prasetyaningrum Pekik Wiji , Kusharyoto Wien
Published: August 2024

The recombinant yeast Pichia pastoris produced insulin precursor (IP) by secreting it extracellularly. Synthetic prepro-leaders were developed for IP secretory expression in Saccharomyces cerevisiae, and we employed a P. pastoris recombinant clone (CL-4) with a synthetic IP-encoding gene in its genome to generate IP. The secreted IP was analyzed using LC-MS/MS analysis to compare it with the theoretical molecular weight. A pulse-batch method was utilized to produce the IP in a 2 l bioreactor. The purified IP was further converted into mature human insulin (HI) through a one-step transpeptidation reaction. The HI was then subjected to a series of steps including crystallization, deprotection, and purification. The IP purification recovery increased by 90% as compared to our previous study. The mass spectrometry (MS) analysis of the IP yielded an identical theoretical molecular weight value of 7072.10 Da. Furthermore, a specific molecular species of 5839.56 Da was detected by intact MS in the purified 1C5 fraction, which is similar to the oxidized form of HI. Based on our in vitro glucose uptake assay, the 1C5 fraction stimulated glucose uptake at a ratio of 0.86 compared to USP HI, indicating the functional presence of HI in the 1C5 fraction.

Beskrivelse og vurdering av tiltaket: Sov bedre!
Authors: Eng Helene , Ulvund Stein Erik
Published: August 2024

Innledning:  Sov bedre! er et miljøterapeutisk foreldreveiledningstiltak til barn med søvnvansker, primært prøvd ut overfor barn med autisme. Formålet er å bedre søvnkvaliteten til barna slik at de er uthvilt på dagtid. God søvnkvalitet for barna har stor betydning for både barnas og de voksnes livskvalitet.
Beskrivelse av tiltaket:  Tiltaket er nytt i Norge, og prøvd ut i forhold til noen familier. Gjennomføringen av tiltaket er 4-delt:1) Kurs. Foreldrene får undervisning i gruppe på 5-6 familier.2) Kartlegging av søvnvaner.3) Individuell utarbeidelse av behandlingsdelen sammen med terapeut.4) Søvnbehandlingen foregår hjemme hos barnet. Foreldrene prøver ut de tiltakene de ble enige med terapeuten om.
Evaluering av tiltaket:  Tiltaket er prøvd ut som et tilbud til 5 familier som hadde barn med autisme. To avbrøt treningen. For alle de 3 barna som var igjen, ble den totale søvnkvaliteten forbedret 6 mnd etter intervensjonsstart. Evidensen fra internasjonale studier for liknende intervensjoner anses som svak fordi mange av studiene har svært få deltakere. Ingen av studiene viser imidlertid noen negative effekter av disse metodene, og det finnes heller ikke alternative behandlingsmåter med bedre evidens over tid.
Ungsinns klassifisering: Tiltaket klassifiseres som et potensielt virksomt tiltak på evidensnivå 1.
Beskrivelse og vurdering av tiltaket: PALS - Positiv atferd, støttende læringsmiljø og samhandling

Innledning: PALS er en skoleomfattende innsatsmodell med mål om å fremme sosiale og skolefaglige ferdigheter samt å forebygge og redusere problematferd blant alle grunnskolens elever (1.-10. klasse). Alle elever og ansatte på skolen involveres i å bygge et trygt læringsmiljø. Atferdssenteret har utviklet PALS og er ansvarlig for opplæring og implementering i skolen.
Beskrivelse av tiltaket: PALS består av universelle forebyggende innsatser som rettes mot alle elever. En mindre gruppe elever (10-15 %) viser moderat til høy risiko for problemutvikling og har ikke tilfredsstillende utbytte av de forebyggende tiltakene. For disse har modellen mer intense, målrettede innsatser på selektert og indikert nivå. Modellen disponerer et bredt spekter av forhåndsdefinerte forskningsbaserte intervensjonskomponenter for å fremme og støtte elevenes læring og utvikling. Konkret innsamlet informasjon benyttes for å avdekke sosiale, atferdsmessige og skolefaglige problemer på et tidlig tidspunkt for å kunne målrette innsatsen i forhold til elevenes individuelle behov for hjelp og støtte.
Evaluering av tiltaket: Det er gjennomført en kvasi-eksperimentelt studie med kontrollgruppe på PALS. Utvalget var fra 8 skoler som inkluderte 704 elever og 82 lærere. Tiltaket viste moderate til store effekter på nedgang i problematferd basert på lærernes tilbakemelding. De fant imidlertid ikke signifikante effekter på elevenes sosiale kompetanse i denne. Analyser av forskjeller mellom de fire PALS-skolene viste en signifikant sammenheng mellom hvor godt PALS var implementert og i hvilken grad programmet klarte å begrense problematferd både på skolen og i klassen. Det pågår en langt større evalueringsstudie av PALS som inkluderer 10 000 elever fra 65 barneskoler fra hele landet.
Ungsinnpanelets klassifisering: PALS klassifiseres som et funksjonelt virksomt tiltak på evidensnivå 3, med dokumentasjonsgrad ***.
Beskrivelse og vurdering av tiltaket: Psykologisk førstehjelp

Innledning: Psykologisk førstehjelp er i hovedsak selvhjelpsmateriell som retter seg mot barn og unge i alderen 8-18 år. Skrinene kan brukes av barna/ungdommen alene eller med sammen en voksen. Fagfolk kan bruke skrinene sammen med barn eller ungdom for hjelp i samtaler om vanskelige tema, som veiledet selvhjelp eller som en del av en behandling. Førstehjelpskrinene er utviklet av psykologspesialist Solfrid Raknes sammen med en faglig referansegruppe.
Beskrivelse av tiltaket: Programmet består av selvhjelpsmateriellet: Førstehjelpsskrinet. I tillegg finnes en veileder for fagpersoner i førstelinjetjenesten. I denne beskrives det hvordan hjelpere kan brukes materiellet i et tilbud om veiledet selvhjelp. Det finnes to skrin med alderstilpasset innhold. Ett for barn i alderen 8-12 år og ett for ungdom i alderen 13-18 år. Ved å bruke materiellet kan barnet eller ungdommen øve på å forholde seg til aktivt egne følelser og gi makt til de positive tankene. De trener på hvordan de kan påvirke opplevelsen av vanskelige situasjoner ved å sortere tanker og følelser.
Evaluering av tiltaket: Tiltaket er forholdsvis nytt og har vært tilgjengelig for et åpent marked fra februar 2010. Det foreligger ingen effektstudier på Psykologisk førstehjelp foreløpig. Det har vært gjennomført undersøkelse av hvordan hjelpere i førstelinjen bruker materiellet. Undersøkelsen har vært grunnlaget for utarbeidelsen av veilederen og et opplæringstilbud.
Ungsinns klassifisering: Tiltaket Psykologi førstehjelp er godt beskrevet og metodene som benyttes er forankret i allment akseptert teori. Fordi det ikke foreligger studier på tiltakets effekt, klassifiseres tiltaket som et sannsynlig virksomt tiltak på evidensnivå 2.
Beskrivelse og vurdering av tiltaket: PIS

Innledning: PIS (Program for implementering av samtalegrupper for skilsmissebarn) er et selektivt forebyggendetiltak for barn og unge som har opplevd foreldres samlivsbrudd. Tiltaket tilbys som samtalegrupper gjennom skolen. Samtalegruppene skal hjelpe barna i å håndtere egen situasjon, frita dem for skyldfølelse og hjelpe dem til å beherske nye mestringsstrategier.
Beskrivelse av tiltaket: Skolegruppene går over 7 skoletimer. Møtene har en fastsatt struktur med temaer som ofte er vanskelig for barn med skilte foreldre. Det er utviklet materiell for 3 alderstrinn der tematikken er den samme, men der materiellet pedagogisk sett er tilpasset barnas alder. Barna jobber med temaene gjennom å reflektere rundt historier om skilsmisser, og det brukes løsningsfokusert tilnærming (LØFT) for at barna skal trene på å finne løsninger i eget liv.
Evaluering av tiltaket: Det er ikke gjennomført noen effektevalueringer av tiltaket i Norge. I en spørreundersøkelse blant barneskoleelever som hadde deltatt i PIS-grupper, rapporterte barna selv at de selv opplevde å mestre stress bedre etter deltakelse i samtalegruppene, og at de synes det er lettere å snakke med foreldrene om belastninger. Svakheten ved denne evalueringen er at det ikke ble gjort noen undersøkelse før tiltaket ble gitt.
Ungsinns klassifisering: Tiltaket PIS har en teoretisk forankring samt et oversiktlig materiell. Fordi det ikke foreligger norske studier på tiltakets effekt, klassifiseres tiltaket som et sannsynlig virksomt tiltak på evidensnivå 2.
